AUTOSTEM BLASTING SOLUTION

Operating Statistics

Autostem cartridges utilised.
A single driller preparing holes, working every second day.
Compressor, rock drill and accessories prices on rental basis.

Total cartridges purchased:
USD 13,862 / EURO 12,182

Machine Costs

Drilling costs:
Compressor rental plus diesel:
USD 51.72 / EURO 45.45per day
Labourer cost:
USD 13.80 / EURO 12.12 per day
Holes drilled per day 70 x – 100 x
Thus drill cost per hole : USD 0.66 / EURO 0.58
Total drill cost per hole x 3,350 holes =
USD 2,211 / EURO 1,943

Costs Per Ton

Total cost of cartridges and drilling:
USD : 13,862 + 2,211 = USD 16,073
EURO: 12,182 + 1,943 = EURO 14,124
Total cost per ton:
USD 16,073 ÷ 10 050 tons = USD 1.60 per ton
EURO 14,111÷ 10 050 tons = EURO 1.41 per ton

TOTAL COST PER TON = USD 1.60 / EURO 1.41

MECHANICAL BREAKER

Operating Statistics

Total number of true operating hours : 540 hours
(Taking into account all: machine downtime, maintenance, part replacements, blasting schedules, miscellaneous)

Equivalent to 67 fully functional days per annum.
Total number of boulders broken = 3,350 (avg. 5o per day)
Tons worked :10,050 ( avg. of 3 tons per cubic meter)

Machine Costs

Purchase cost: USD 103,449 / EURO 90,909
( excluding, moil )( 2,500 hours machine life )
540 hours worked per annum, thus a work rate of USD 41.38 / EURO 36.37 per hour
Equipment expense: USD 22,345 / EURO 19,637
Maintenance costs: USD 18,931 / EURO 16,637
Operator costs: USD 4,966 / EURO 4,364
Diesel costs: USD 22,180 / EURO 14,491

Costs Per Ton

Total machine cost ÷ tonnage processed:
USD 68,422 ÷ 10,050t = USD 6.81 per ton
EURO 55,129 ÷ 10,050t = EURO 5.49 per ton

TOTAL COST PER TON = USD 6.81 / EURO 5.49
