Introduction. The unit cost of logging or road construction is essentially derived by dividing cost by production. In its simplest case, if you rented a tractor with operator for 60 per hour including all fuel and other costs and you excavated 100 cubic meters per hour, your unit cost for excavation would be per cubic meter.

Depending on the size of mining entries, stopping sizes range from as small as 4ft by 20ft in low coal to as large as 30ft by 40ft in limestone mines. 2. Overcast/undercast Overcasts are air bridges where intake and return airways are required to cross each other.
Can Size. Based on discussions with several leading idler manufacturers, can size is the one factor that can directly affect roller life.* In the case of idlers, size does matter, and there is a rule of thumb: 4" cans for 400 FPM, 5" for 500 FPM, and so on.
is less than half the size of the wirecloth opening. The higher the percentage of small feed material the greater the screen capacity. The faster the material passes through a screen the more open area there is left to screen the remaining material. A feed material with 40% of the feed being half the opening size or smaller equates to a factor ...
