通过研究微震监测系统的能量变化判断工作面发生冲击地压的区域,其原理是由检测器测量探针接收P波和S波信号的第1次到达时间,在一定条件的波速场下进行三维立体定位,来确定能量发生变化的准确区域,并通过计算震相的持续发生时间来计算所释放的能量和震级,确定危险等级,将其标入采掘工程图并速报显示给生产指挥体系,以便及时采取应对措施,为矿井的安全高效生产创造良好的条件。
By studying the energy variation of the microseismic monitoring system to determine the area of rockburst on the working face, the principle is that the probe receives the first arrival time of the P-wave and the S-wave signals by the probe and performs three-dimensional Dimensional positioning to determine the exact area of energy change and calculate the release of energy and magnitude by calculating the duration of the seismic phase to determine the hazard level, which will be marked into the mining engineering drawings and displayed to the production command system, In order to promptly take response measures for the safe and efficient production of mines to create good conditions.
