Sensors of movement of the executive body of mining machines

Abstract

Unmanned excavation of coal is possible only with automatic control of the position of the executive body of the mining machine according to the power of the seam. Reliable operation of drilling machines, as well as other drilling machines, at considerable depth of boreholes 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 executive body of mining machines and depending on changes in hypsometry and formation power, is of great importance.
