Movement sensors of movement of the working member executive body of mining machines

Abstract

Unmanned excavation of coal is possible only with automatic control of the position of the working member of the mining machine according to the thickness of the seam. Reliable operation of drilling-and-cutting machines, as well as other drilling machines, at considerable borehole depths can be ensured only by effective sensors determining the boundary "coal - rock" in the borehole. Creation and implementation of workable automatic devices that control the position of the working member of mining machines depending on changes in hypsometry and seam thickness, is of great importance.
