Study of the parameters and methods of load flow stabilization for short-cut continuous mining machines (potash deposits)

Abstract

1. In continuous chamber mining, the structural dominant of the random function of the cumulative flow in frequency terms is described by a two-component system formed as a combination of a relatively slowly varying curve and a high-frequency component; they are generated by cyclic property of chamber working and delivery cycles, respectively. 2. The high-frequency component of the load can be eliminated by under-chamber ore closing, minimizing losses; stabilization of the flow in low-frequency component can be achieved by general mine hoppers (storage areas). The hopper capacities are determined from the control characteristic as a function of the average incoming load flow and under-hopper conveyer (feeder) reserve. The type and the parameters of stabilizing members planned for specific mining conditions should be determined by cost and engineering analysis.
