摘要
埋藏深度大、顶板存在坚硬厚岩层、煤层强度高和断层地质构造的煤层,具有一定的冲击危险性。以巴彦高勒煤矿正在进行回采的311305工作面作为示范回采工作面,对采动过程中以及顶板跨落前后的声电信号变化规律进行实时监测和采集,掌握煤岩动力事件发生前后声电监测信号的变化规律,从而指导井下安全生产工作的正常运行。
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 demonstration 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.
