ESTIMATING SCOOPTRAM MUCKING TIME ANO OISTANCE FOR TUNNELS~

RAMPS ANO MINE OEVELOPMENT

t~ IIMAIINIi IUNNtL ANU KAMI'

MUCKING DISTANCE In driving TUNNELS and RAMPS, the MAJOR ELEMENTS of the total cycle of ADVANCE are DRILLING, LOADING, BLAST/SMOKE OUT, SCALE, MUCK OUT and often, . The key to economical operation is found in blending these cycle components into TIME FRAMES that fit into the overall plan for advancing once, twice, possibly three times in a 24 hour periodo

FIG. 8 illustrates that after blasting, it may be necessary TO SCALE the back BEFORE MUCKING can begin. The Scooptram may or may not be employed for this and the time it takes may or may not be included in the mucking cycle. Identify this with your customer.

Our part of the total cycle of ADVANCE is MUCKING OUT and the first question asked will often be, "HOW FAR can we MUCK the HEADING within a specified ALLOTTED TIME with a Scooptram?" If the loose cubic yards to be moved each blasting round and the allocated mucking time are known, you can provide a quick, rough estimate using the SCOOPTRAM PRODUCTION CHART on page 61, English; 62 Metric. However, important elements of the TOTAL CYCLE are not taken into in using the production chart and FIGURES 8 and 9 illustrate two elements of ihe cycle that could affect that estimate.

FIG. 9 illustrates that as long as there is plenty of muck available to move from the blasting round, production can go forward in a normal, load/tram/dump cycle at the best speeds possible. It also illustrates that THE DISTANCE FROM THE PORTAL TO THE DUMP can have an effeet on the actual TUNNEL MUCKING DISTANCE. The TIME it may take to tram from the PORTAL to the DUMP must be SUBTRACTED from the TRUE DISTANCE OF TOTAL TUNNEL ADVANCE IN THE ALLOTIED MUCKING TIME. The possible time and distance loss from this factor and possibly other factors of the dump point affecting total tunnel advance, should be discussed and accou nted for.

Figure 9 A final factor must be taken into consideration and that is the time itmay take to "CLEAN UP" the face of the tunnel for the next drilling cycle.

:STIMATING TUNNEL AND RAMP MUCKING DISTANCE -"':IG. 1O illustrates that as the MUCKING CYCLE progresses, the MUCK PILE DIMINISHES. To get a lUCKET LOAD WORTH TRAMMING, the Scooptram nust make several es with the effect of increased -ruading time and decreasing productivity to "CLEAN UP." .dditional/y, some FACE PREPARATION for the next -dRILLlNG CYCLE may be a chore for the Scooptram.

-On especially long tunnels or where other activities in it prevent this approach, TWO SCOOPTRAMS may be employed, one cleaning the face to the station, the other cleaning the station to the portal so as lo maintain allotted llucking time al/ the way from the face to the portal.

ESTIMATING MINE TRUCK PRODUCTION

VEHICLE SELECTION:

As has been discussed for Scooptrams on page 5, Scoopy reminds us we usually select the LARGEST CAPACITY vehicle that will "FIT" the mine with REASONABLE or REGULATED CLEARANCES between the back, the mine walls and/or vent, air and electrical lines. that the less the clearances, the slower the tramming speed and therefore, the lower the production and the higher the cost per ton to produce. BE SURE THE TURNING RADIUS OF THE MINE TRUCK WILL PERMIT 90 DEGREE TURNS THROUGH INTERSECTIONS WITH REASONABLE CLEARANCES. (See page 57 for the English system, page 59 tor the metric system.) 30

The same rules ot OVERLOADS and UNDERLOADS dls cussed tor Scooptrams on page 13 apply to MINI TRUCKS. Estimators are urged to consult with Wagner Mining Equipment Co. for recommendations on blocking out volume capacity, adding sideboards or re-desiqnin: the truck box to take full advantage of truck RATED C/l_ PACITY where material weight per cubic measure tind a substantial OVERLOAD or UNDERLOAD condition.

I STIMATING MINE

TRUCK PRODUCTION APPLlCATION: Major considerations are, TWO or FOUR WHEEL DRIVE, style of DUMPING, OPERATOR SEATING d, of course, ELEVATION above sea level where the vehicle will work.

é

I .vel or near level on HARD SURFACES, wet or dry but I )T SLlPPERY.

Level, near level SOFT SURFACES, high rolling resistance or hard but very SLlPPERY.

Grades to 12%if DRY, good TRACTION. Beware of wheel ,"'''IN-OUT if slippery or loose floor at 9% to 13%grade.

Grades steeper than 10%, wet, slippery, poor traction for any other reasons.

~-rYLEOF DUMPING: If hauling out of the mine or if the underground dumping point can be provided with a chamber of sufficient height, the "TIP" dump, (MT), may be preferred because of fewer hydraulics to maintain. For durnp I »nts with RESTRICTED DUMP HEIGHT or where METERED dumping is required, the telescoping MTI or MTP I__ ay be required. Those two models have two other advantages to consider, FASTER DUMP TIME because you don't wait tor the box to come back down and SAFETY beca use the box can never be inadvertently raised or fail ~~be lowered, causing accidents. bPERATOR SEATING: Some models are standard with SIDE SEATING, others with DUAL CONTROLS and a turn table seat allowing 180 degree facing of the operator, forward and backward. Some models offer an optional I ioice between the two seating arrangem ents. SIDE SEATING offers a single set of controls for fewer parts and I 3S maintenance but possibly less operator visibility when backing and/or less overall operator comfort. DUAL CONTROLS present more maintenance cost but may be preterred tor very long hauls, especially when BACKING Inl1gdistances where the operator cannot SEE OVER the load or the empty truck box. LWLOAD:

As with Scooptram buckets, a HEAPED LOAD is based on mathematically calculated VOLUME within and on TOP of the truck box. It would assume the front corners are completely filled, that the HEAP is as specified and even with the truck side boards. SCOOPY illustrates that it is certainly TIME CONSUMING, if not IMPOSSIBLE to CONSISTENTLy load a truck to its RATED VOLUME and, therefore, its RATED TONS.

As we know, our Mine Truck models are rated in TONS ti8dto MATERIAL WEIGHT PER CUBIC YARD or CUBIC ETER. If a model number does not call out a specific ~aterial weight, it is taken to be 2700 lbs. y3, (1600 kg/m3). The VOLUME CAPACITY is assumed to be SEMI . 'OMINAL* HEAPED LOAD and is found with: (Model designated TONS) x (2000) (Model designated material weight, lbs. y3) ubic yards x 0.765

=

= __

TABLE 1A in the estimating form on the foliowing pages suggests "FILL FACTORS" to apply to adjust for this fact in estimating PAYLOADS. Loading with belts or flights with horizontal swing capability or with chutes of proper design are the methods most likely to produce FULL LOADS. Fixed belts or flights, improperlydesigned chutes reduce the potential for full loads. Loading with Scooptrams or other front end loaders finds an EOD bucket offering the best chance for full, heaping loads while the standard, tipping bucket offers the least potential. Front end loaders mis-matched to the job are least likely to heap the load. If the loader maximum dump height finds the bucket Iip INSIDE the truck box or if restricted BACK HEIGHT forces the lip down into the box, consistently heaped loads will be impossible to achieve.

The Mine Truck selected is usually the largest capacity that will "FIT" into the mine with REASONABLE or REGULATED CLEARANCES between the mine walls, back or ancillaries. UNE 3 ,. self explanatory. UNE 4. As discussed in Catalog 150A on page 31, a FULL, RATED LOAD is extremely difficult to achieve exce] with belts or flights with horizontal swing capabilities.

Section 11:UNE 5. Self explanatory. However, use CAUTION in acceptinq a manufacturer's rating of TABLE 1A PRODUCTION for the loading machine. It will probably be based on certain OPTIMUM JOB CONDIJOB FILL TIONS that may not be achievable in a specific operation. UNE 6. LOADING WITH SCOOPTRAMS, CONDITIONS FACTOR 1: etc. Two separate problems are possible, i.e. LOADER NOT SELECTED (1) or LOADER ON SITE EXCELLENT 1.00 OR ALREADV SELECTED (2).

As a RULE, less than FOUR loader SEVERE 0.96 I ES finds the bucket size UNWIELDL y dumping into the truck box while more than SIX ES may find loading TIMES too LONG. (NOTE: in underground mining the bucket size that may fit the operation, (back height, truck box height), will often be the deciding factor in what size loader/bucket can be employed.) F( estimating purposes, assume 5 bucket es to load the truck. Then find OPTIMUM BUCKET SIZE with: (1) Une 3 VOLUME / ~/ 3 (Number of es~)

We suggest you always ROUND TO THE NEXT HIGHER quarter, half or whole size bucket if the loader will carry that size The theory is that it is easier NOT to get a fullload every . The operatoi, can make one "Iight" or simply not dump all of the last on the truck box. Now select a "FILL FACTOR" from TABLE 1A just as you would for Scooptram production and find the potential PAYLOAD of the truck with; (Bucketsize

TABLE lA, below, suggests "FILL FACTORS" to apply at UNE 4 to adju: PAYLOAD to a value experience tells us can actually be ACHIEVED. Section 11:UNE 5. Self explanatory. However, use CAUTION in accepting a manufacturer's rating of TABLE 1A PRODUCTION for the loading machine. It will probably be based on certain OPTIMUM JOB CONDIJOB FILL TIONS that may not be achievable in a specific operation. UNE 6. LOADING WITH SCOOPTRAMS, FACTOR CONDITIONS etc. Two separate problems are possible, i.e. LOADER NOT SELECTED (1) or LOADER ON SITE EXCELLENT 1.00 OR ALREADY SELECTED (2). Assume the loader has NOT BEEN SELECTED. First establish the OPTIMUM SIZE BUCKET to match the selected MINE TRUCK. As a RULE, less than FOUR loader 0.98 AVERAGE ES finds the bucket size UNWIELDL y dumping into the truck box while more than SIX ES 0.96 SEVERE may find loading TIMES too LONG. (NOTE: in underground mining the bucket size that may fit the operation, (back height, truck box height), will often be the deciding factor in what size loader/bucket can be employed.) Fe estimating purposes, assume 5 bucket es to load the truck. Then find OPTIMUM BUCKET SIZE with: 3 (1) (Une 3 VOLUME/O. 9L¡5 m ) = .2./1'1 m3 = 2. y3 OPTIMUM BUCKET SIZE.

AND OPERATING COST ESTIMATING

A vehicle may PRODUCE at the desired rate but productivity must be at a COSTallowing PROFITABLE PRODUCTION. Costs are divided into OWNERSHIP and OPERATING categories. Essentially, OWNERSHIP costs are made up of INVESTMENT and DEPRECIATION values and are charged against PRODUCTIVITY of the vehicle on an HOURL y BASIS. This theoretically provides a RESERVE of CAPITAL with which to replace the vehicle when it is no longer ECONOMICALL y SERVICABLE. HOWEVER, many countries encourage capital investment with special tax laws and credits that may have the effect of recovering invested capital by means OTHER THAN CHARGING IT AGAINST PRODUCTIVITY. This should be discussed with your customer who will usually want to use his own formulas based on local customs and tax laws to compute OWNERSHIP COSTS. Using the STRAIGHT UNE method we suggest in our estimating form will usually result in much HIGHER OWNERSHIP COST than would be shown using more sophisticated methods used by most companies. OPERATING COSTS cover the HOURL y cost to operate, maintain and repair the vehicle over its expected usefullife. These costs vary widely for an infinite number of reasons not only applying to JOB CONDITIONS but to DIFFERENCES in LABOR and PARTS COSTS in different areas of the world. On the following pages, our estimating form and instructions establish GROUND RULES based on certain ASSUMPTIONS that will allow us to compare similar items with our competitors. The formulas use FACTORS that may be adjusted to reflect experience or records. The tables provide suggested figures to use but may be interpolated to reflect experience or records. THE METHODS SUGGESTED, FIGURES GIVEN AND FORMULAS USED ARE FOR ESTIMATING PURPOSES ONLY AND NO GUARANTEE IS OFFERED THAT RESULTANT COST ESTIMATES CAN BE ACHIEVED IN A GIVEN SITUATION.

SECTION 1:UNE 1 through UNE 5 are self explanatory. SECTION 11:OWNING COSTS: UNE 6 is self explanatory. UNE 7. YEARS TO DEPRECIATE is found by first establishing ESTIMATED TOTAL USEFUL HOURS of vehicle SERVICE UFE. TABLE 6 suggests AVERAGE, ECONOMICAL, USEFUL SERVICE UFE related to the same JOB CONDITIONS discussed in the production estimating section, Catalog 150A. Do not hesitate interpolating TABLE 6 if it is known different values are to be expected. Take selected hours to UNE 7. After com pleting line 7, and rounding to the next higher number of years, TABLE 7 provides an ANNUAL INVESTMENT FACTOR, applied to spread delivered price over the depreciation period in years. Enter the factor in the formula at UNE 8. Continue with UNE 8 by estimating l., 1.&T. percentages. INTERESTrefers to the cost of borrowing money to buy the machine and could run from 8 to 12% and higher. On the other hand, if held capital is used to buy the vehicle, INTEREST charges would be those that would have been EARNED by investing the money to earn interest and might range from 4 to 8%. INSURANCE refers to costs to protect the vehicle from damage or loss to accidents, fire, etc. and in 1976 may range from 3 to 5%. Taxes refer to ongoing use, property etc. Establish or estimate applicable percentages for the time, place and situation, adding together for total l., 1.& T. For estimating use 12% at line 8.

The Low High Average Engine Model low column suggests LONG TRAMMING DISTANCES on LEVELor NEAR LEVEL 1.7 0.9 2.6 F4L-912W haulageways. The high column suggests VERY SHORT DISTANCES or STEEP RAMP operations. ESTIMATING AVERAGE HOURLY FUEL CONSUMPTION IS 1.3 3.9 2.6 F6L-912W RATHER IMPRECISE andyou should understand how it works. Most engine 2.4 7.2 4.8 F6L-714 manufacturers establish fuel consumption rates on a DYNOMOMETER with 3.2 9.7 6.5 F8L-714 DIRECT DRIVEand provide a curve showing fuel consumption in POUNDS PER 8.1 4.1 12.2 F10L-714 HOUR or GALLONS PER HOUR at that power and r.p.m. point. In a normal auto4.9 14.8 9.9 F12L-714 motive type application the horsepower need during an hour period will fluctu6.4 19.1 12.7 BF12L-714 ate greatly so we have to make an estimate and come up with our TABLE 8 of 1.7 3.5 5.3 AVERAGE CONSUMPTION and REFLECTING THE HIGHER CONSUMPTION OF 3304 NA 5.2 TOROUE CONVERTER DRIVE. The point being made is that if a competitor with 2.6 7.9 3306 NA the same type of equipment with the same engine comes up with a substantially Liters = gal. x 3.7854 lower consumption than given in TABLE 8, he is using a DIRECT DRIVE BASIS or assuming a LOWER AVERAGE HORSEPOWER REOUIREMENT, or both. UNE 12. PREVENTIVE MAINTENANCE: The cost ( lubricating oils, filters, grease and the labor to use them in the daily care and feeding of the vehicle are assumed as a per centac of FUEL COSTS. This assumes that the more fuel used, the larger the engine and equipment and preventive maintenance cosrs: will rise accordingly. Do not hesitate usinga different percentage if records or experience dictate. UNE 13 is self explanatory if repair costs are known from records or experience. If not known, the costs may be estimated using the formula at UNE 13(a' The formula assumes: 1. A vehicle will generate REPAIR COSTS equal to 75% of its FACTORY UST PRICE over its useful life. The 75% figure applleer REGARDLESS of JOB CONDITIONS simply being expended faster over a shorter useful life, slower over a longer useful life. You can adjust the 75% figure up or down if experience dictates. Be sure to use unit list price plus on site costs rather than delívere -' price if different. 2. Repair costs are divided equally, 50% labor, 50% parts and assume labor at U.S. $8.00 per hour, parts at suggested list pricb-;f.o.b. Portland. If you know that in your part of the world, labor costs 30% less than $8.00 but you must sell parts 20% higher than suggested list price, you would decrease the hourly cost by 10%,30% less 20% = 10%.

However, use CAUTION in accepting a manufacturer's rating of TABLE 1A PRODUCTION for the loading machine. It will probably be based on certain OPTIMUM JOB CON 01JOB FILL ~ TIONS that may not be achievable in a specific operation. UNE 6. LOADING WITH SCOOPTRAMS, CONDITIONS FACTOR etc. Two separate problems are possible, i.e. LOADER NOT SELECTED (1) or LOADER ON SITE EXCELLENT 1.00 OR ALREADY SELECTED (2). Assume the loader has NOT BEEN SELECTED. First establish the , AVERAGE 0.98 OPTIMUM SIZE BUCKET to match the selected MINE TRUCK. As a RULE, less than FOUR loader SEVERE 0.96 I ES finds the bucket size UNWIELDL y dumping into the truck box while more than SIX ES may find loading TIMES too LONG. (NOTE: in underground mining the bucket size that may fit the operation, (back height, truck box height), will often be the deciding factor in what size loader/bucket can be employed.) FI estimating purposes, assume 5 bucket es to load the truck. Then find OPTIMUM BUCKET SIZE with:

y3 OPTIMUM BUCKET SIZE. We suggest you always ROUND TO THE NEXT HIGHER quarter, half or whole size bucket if the loader will carry that SiZE , The theory is that it is easier NOT to get a fullload every . The operato can make one "Iight" or simply not dump all of the last on the truck box. Now select a "FILL FACTOR" from TABLE 1K just as you wouldfor Scooptram production and find the potential PAYLOAD of the truck with; (1)

------------------------------------------------------------------------------------~~ Section 1: GENERAL DATA: UNE 1 is self explanatory. UNE 2. The Mine Truck selected is usually the largest capacity that will "FIT" into the mine with REASONABLE or REGULATED CLEARANCES between the mine walls, back or ancillaries. UNE 3 iself explanatory. UNE 4. As discussed in Catalog 150A on page 31, a FULL, RATEO LOAD is extremely difficult to achieve excer with belts or flights with horizontal swing capabilities. TABLE 1A, below, suggests "FILL FACTORS" to apply at UNE 4 to acjus., PAYLOAD to a value experience tells us can actually be ACHIEVED. Section 11:UNE 5. Self explanatory. However, use CAUTION in accepting a manufacturer's rating of TABLE 1A PRODUCTION for the loading machine. It will probably be based on certain OPTIMUM JOB CONDIJOB FILL TIONS that may not be achievable in a specific operation. UNE 6. LOADING WITH SCOOPTRAMS, FACTOR . CONDITIONS etc. Two separate problems are possible, Le. LOADER NOT SELECTED (1) or LOADER ON SITE EXCELLENT 1.00 OR ALREADY SELECTED (2). Assume the loader has NOT BEEN SELECTED. First establish the OPTIMUM SIZE BUCKET to match the selected MINE TRUCK. As a RULE, less than FOUR loader 0.98 -T AVERAGE ES finds the bucket size UNWIELDL y dumping into the truck box while more than SIX ES SEVERE 0.96 I may find loading TIMES too LONG. (NOTE: in underground mining the bucket size that may fit the operation, (back height, truck box height), will often be the deciding factor in what size loader/bucket can be employed.) Fo estimating purposes, assume 5 bucket es to load the truck. Then find OPTIMUM BUCKET SIZE with: (1) (Une 3 VOLUME m3) 3 3 ____ m = y OPTIMUM BUCKET SIZE We suggest you always ROUND TO (Number of es --) 0.765 THE NEXT HIGHER quarter, half or whole size bucket, y3 x 0.765 = m3. The theory is that it iseasier NOT to ge~ a full bucket load every , the operator can make one "Iight" or simply not dump all of the last on the truck box Now select a "FILL FACTOR" from TABLE 1Ajust as you would for Scooptram production and find the potential PAYLOAD with (Bucket size __ m3) x (es __ ) x (Line 1 weight tonnes) x ("FILL FACTOR" __ )= tonnes/PAYLOAD_

Do not hesitate interpolating TABLE 6 if it is known different values are to be expected. Take selected hours to LlNE 7. After completing line 7, and rounding to the next higher number ofyears, TABLE 7 provides an ANNUAL INVESTMENT FACTOR, applied to spread delivered price over the depreciation period in years. Enter the factor in the formula at UNE 8. Continue with UNE 8 by estimating l., 1.&T. percentages. INTERESTrefers to the cost of borrowing money to buy the machine and could run from 8 to 12% and higher. On the other hand, if held capital is used to buy the vehicle, INTEREST charges would be those that would have been EARNED by investing the money to earn interest and might range from 4 to 8%. INSURANCE refers to costs to protect the vehicle from damage or loss to accidents, fire, etc. and in 1976 may range trorn 3 to 5%.Taxes refer to ongoing use, property etc. Establish or estimate applicable percentages for the time, place and situation, adding together for total l., 1. & T.

tJATERIAL WEIGHTS

T 3 precise measurement of material weight is expressed as its SPECIFIC GRAVITY which is a number indicating h...,..w many times a VOLUME of material is HEAVIER than a volume of PURE WATER at 62 degrees F. The weight of one cubic inch of such water is 0.0361 pound. If specific gravity is known, the "IN BANK" weight of a material F-R CUBIC VARO is found by multiplying the specific gravity by 1,683.6.

PRECISE weights of "LOOSE" materials per cubic measure are difficult to estimate because of variables in fragmentation achieved in blasting. Usually, your customer will have established AVERAGE "LOOSE" WEIGHT per cubic measure from TESTING. If weights are not established, TABLE 16 provides ESTIMATEO AVERAGE WEIGHTS of some materials. CAUTION: These are AVERAGE weights and it should be understood that material having the same name can vary greatly in weight depending on ore content, moisture, etc. If the customer has a precise knowledge of the "IN BANK" weight derived from a specific gravity number, you need only to estimate the % SWELL after blasting and find the swell FACTOR to estimate "LOOSE" WEIGHT.

=

100 _ 145 - 0.69

"IN BANK" 3950 lbs. x 0.69 factor = 2725 Ibs./y3, the "LOOSE" WEIGHT PER CUBIC VARO.

THEORETICAL TURNING CLEARANCE GRAPH CAUTION: Completing this graph in accordance with the instructions given below provides a graphic illustration of theoretical clearances available between a vehicle, the outside walls and inside corner of a ninety degree drift intersection. Actual clearances achieved depend on the exact position of the vehicle when the turn is started and the distance travelled before full steering angle is achieved. From the specification

sheet, fill in turn radii dimensions.

A. WHERE EXISTING DRIFTWIDTHS

ARE KNOWN:

1. Starting at the apex D, scale outward on both the A and B scales the dimension of the outside turning radii and place marks representing that dimension. 2. Now assume some clearance is required between the vehicle side and the mine wall at the start of the turn, (probably not less than two feet but could be more or less depending on job conditions.) On both the A and B scales, scale outward from the marks representing the outside turning radii the distance selected for clearance and place a mark representing the minewall. 3. On the A scale, start from the mark representing the mine wall and scale inward toward the apex D the actual widtf of the drift and place a mark. Do the same on the B' scale. Now these two marks with a horizontal and vertical line meeting at the C scale to represent the corner of the two drifts. In case the drift widths are different, the lines will meet either above or below the C scale. 4. Starting at the apex D, scale outward on the C scale and place a mark representing the inside turning radius.
