煤岩中弹性能量的表征与冲击地压预测方法研究

Characterization of Elastic Energy in Coal and Rock and Forecasting Method of Rock Burst

分析了煤岩储能区冲击效应现象的发生机理及基本特征,深入探讨了围岩深部原生煤岩体固有的弹性能以及冲击效应的特征;揭示了冲击效应诱发煤岩力学性能及物理性质的变化。基于这些有意义的变化,探讨性地提出了冲击地压的应力监测法和能量型磁电监测法的技术思想,为冲击地压的预测提供了新的方法。

In this paper,the occurrence mechanism and basic characteristics of rock-burst effect phenomenon in the energy storing area in coal and rock mass are analyzed.The elastic strain energy in native coal and rock mass in the depth of surrounding rock and the characteristics of rock-burst effect are discussed.The changes of mechanical properties and physical properties of coal and rock due to rock-burst effect were disclosed.And based on above significant changes,the technical thoughts of stress monitoring metho...
