采空区动力灾害监测的非平衡信号的子波变换分析

Wavelet analysis in dynamical and acoustic emission un-equilibrium monitoring signal of large volume mined-out area

子波变换分析对大采空区动力灾害声发射监测的信号特征分析有很大的优势 ,本文尝试将子波变换技术应用在采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 ,结合统计力学的理论 ,对大采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。这为工程信号中奇异点的探测与识别和矿山采空区动力灾害声发射监测信号识别提供先进。

The characters of the acoustic emission(AE) monitoring signal and advantage of wavelet analysis in the process of the rock damage and crack in the minedout area have been estimated, and applied the wavelet analysis to the dynamical and unequilibrium monitoring signal. Based on the insitu project analyzing and evaluating, and combining the theory analysis of statistical mechanics, the appropriate damage position and crack place have been inferred in the paper.
