| 摘 要： | 试验研究表明,煤岩在冲击破裂过程中,裂缝的形成和颗粒的摩擦会产生电磁辐射,煤岩体所受的应力越高、变形破裂越强烈,电磁辐射信号越强.在冲击地压发生前,煤岩电磁辐射将有较大幅度增加,通过捕捉电磁辐射能量来确定预测冲击矿压危险的临界指标.

| Abstract: | Experiment research shows that,during the impact and rupture process of coal or rock,fracture formation and particles friction can produce electromagnetic emission.The higher stress the coal-rock endures,the bigger deformation and fracture are and the stronger the electromagnetic emission signal is.Before the rock burst occurs,the electromagnetic emission would increase substantially,therefore the critical threshold of rock burst can be predicted by measuring the emission energy. |
