断层冲击地压发生的理论与试验研究
|
摘要
把断层冲击地压看成是断层带与上下盘围岩系统的变形失稳，建立了扰动响应稳定性判别准则，并对断层冲击地压的一个简单模型进行了解析分析。通过粘滑失稳模型，解释了断层冲击地压的间歇性。对断层冲击地压进行了模拟试验，解释了只有达到一定开采深度才可能发生冲击地压，证实了冲击地压发生的间歇性。
The fault rockburst is considered as a deformation destabilization phenomenon of fault and surrounding system. The disturbance-response stability criterion is given. By the analysis of a sample fault rockburst model, the effects of coal mining, mechanical characteristics of surrounding rock and coal mining depth on fault rockburst are studied. A stick-up destabilization model is established and the oscillation of fault rockburst is illustrated. At the end, the equivalent material simulation test of fault rockburst is carried out. It is proved that the coal mining can induce fault rockburst and some phenomena of fault rockburst measured in situ are proved by the test.
