Analysis of approaches to measuring the rock mass volume and composition for automated control system for longwall top coal caving

The article analyzes various approaches to measuring the rock mass volume and composition in the conditions of longwall top coal caving. The approaches corresponding to the mining conditions under which the release is carried out are identified and described. One of the approaches is to measure the rock mass sample based on machine vision system operation combined with light markers grid projection. In addition, a method for estimating the rock mass composition using the gamma method. The necessity of conducting experiments on specialized work benches to determine the composition and volume dependencies under the selected approaches conditions is substantiated. The schemes of conducting experiments processes system-functional modeling on work benches are presented. The requirements for their development based on the technical and technological limitations of the release environment have been established.
