摘要
路基下采空区动力灾害监测是西部矿山多年来一直关注的焦点问题。将子波变换技术应用在路基下空区动力学破坏监测的非稳态信号分析中,基于现场的工程分析与评价,结合数值计算和统计力学的理论,对空区围岩非稳态破坏位置进行了统计推断以及对断裂位置正确定位。结果表明,该方法和技术是可行的。
The characters of the AE monitoring signal and advantage of wavelet analysis in the process of the rock damage and crack in the mined area under roadbed were estimated,and the wavelet analysis was applied to the dynamical and unstable monitoring signal. Based on the insitu project analyzing and evaluating in detail, hybrid the theory analysis of statistical mechanics,the appropriate damage position and crack place were inferred. These verified the new data mining connecting with the rock crack mechanism in order to essentially analyze and predict the rock crack information and unstable damage process.The results show that this method is feasible.
