Monitoring of Coal and Rock Mass Conditions, Coal Mine Air and Extraction Equipment State

摘要

The article discusses development and application of monitoring of rock mass,mine air and mining machinery in the course of mining.The author considers methods of detecting hazardous events based on various physical parameters taken by sensors in rock mass (stresses,seismic emission,acoustic emission,thermal radiation) and in mine air (concentrations of gases,air velocities,pressure,drawdown).The proposed mathematical model takes into account the cause-andeffect relationship in the mining machine-rock mass-mine air-mining machine circuit.
