Response mechanism of acoustic and electrical monitoring signal in mining space and analysis of precursor characteristics of rock burst
Coal seams with large burial depth,hard and thick roof strata,high coal seam strength,and fault geological structures have a certain degree of impact risk.This article took the No.311305 working face currently being mined in Bayan Gaole Coal Mine as a dem-onstration mining face,real-time monitoring and collection of the changes in acoustic and electrical signals during the mining process and before and after the roof falls were carried out to grasp the change law in acoustic and electrical monitoring signals before and after coal rock dynamic events occur,thus guiding the normal operation of underground safety production work.
