Procedure to determine weighted average capacity of machine chains in potash mines

The article feeds information on operation of machine chains in potash mines. Prediction of working capacity of such machine chains using the known engineering procedures involves huge amount of computation and features high labor input. It is of the current concern to develop a simplified procedure for working capacity prediction. The main dependences from the known engineering procedures for determining capacity of machine chains in potash mining are presented and analyzed. The capacity of a chain of machines in a roadway varies subject to the haulage distance. In the initial phase in the roadway, the machine chain capacity equals the unit capacity of the continuous miner. In the second phase, the continuous miner operation involves breaks connected with loading of a self-propelled car, and the machine chain capacity is governed by the capacity of the car. In the third phase, the continuous miner is in the wait mode in the period of the car loading and absence. Consequently, as face is advanced, capacity of the chain of machines lowers. It is proposed to calculate the weighted average capacity of the machine chain using conditional units of work, which represent quantity of ore for haulage by self-propelled car per unit time for preset distance. The proposed procedure offers less labor input. The capacity values calculated using this procedure coincide with the results of the known engineering procedures at imprecision not higher than 1%.

Keywords: machine chain, weighted average capacity, conditional units of work, potash ore mining, roadway.
