煤岩中弹性应力波的传递及监测方法

Transmission as well as monitoring and measurement method of elastic stress wave in coal and rock

基于煤岩体中弹性能的表征分析及能量传递原理,提出煤岩中弹性波的传递模型,利用弹性波的传递方程,分析了波的传播及引起的煤岩介质、能量的各种物理变化,如微震、地音、孔裂隙发育等变化机理。在冲击地压监测原理分析的基础上,探讨了三角形网法的原理及检测思想。

Based on characterization analysis and the energy transfer principle of the elastic energy in coal and rock mass,an elastic wave transmission model was presented in this paper.With the elastic wave transmission equation,the paper in detail analyzed and researched the different physical changes caused by wave transmission,such as the micro seismic,earth sound,pores and fissures development.Base on the analysis of the rock burst monitoring principle,the paper discussed the principle and measurement idea of th...
