Construction and Maintenance of Belt Conveyors for Coal

by belt velocity provides volume of material being transported in unit time. Thus belt conveyor’s ability to transport material is volumetric in nature. The transported volume is converted into tonees (1 metric tonee = 1000 kg) by multiplying it with the ‘Bulk Density’ of the material, in the condition as it is on the belt.

Optimum bunker size and location in underground coal mine

The transportation of coal out of a mine is usually done by a serially linked system of conveyors. It is apparent that in a serially dependent system of this type the failure of any one component (conveyor) causes the complete system to be shut down. The provision of bunkers at strategically located points in the conveyor system can result in the production of coal even in the event of failure
