摘要
根据声发射机理,利用岩石损伤学的原理,研究了声发射与冲击地压之间的内在联系,从而得出声发射技术用于预测冲击地压的可行性,并在冲击地压比较严重的老虎台煤矿进行了声发射技术试验。现场试验过程中,工作面发生的5次冲击地压均被声发射仪器监测到,证明了声发射技术可用于预测冲击地压。
Study was made on the inner link between AE and rock burst according to AE mechanism and rock damage principle, thus a conclusion was drew that it is feasible to use AE theory to predict rock burst. Tests on AE were conducted in Laohutai Coal Mine where more serious rock burst exists. The field tests showed that 5 rock bursts occurred in coalfaces were all detected and monitored by AE apparatus, this proved that AE theory can be successfully used for the prediction of rock burst.
