中文摘要：
基于大面积采空区上覆岩层垮落灾害事故案例综合分析与研究,探讨了近年来出现的一种特殊矿山煤岩动力现象,即采空区顶板大面积垮落诱发矿震与气体动力冲击。通过分析论证了矿震发生前期的动力演变与时空尺度,应用能量转换与守恒理论,揭示出采空区矿震表征及动力冲击要素构成的时空关联尺度,提出将声发射监测技术作为矿震预报的基础与手段,并提出了运用线定位法对震源定位的基本原理。使用声发射监测系统对采空区顶板活动进行在线监测,为采空区矿震监测预报提供一种有效途径。
英文摘要：
Based on the comprehensive analysis and study on the overburden strata falling disaster cases occurred in the goaf with large area,the paper discussed a special mine coal and rock dynamic phenomena occurred in the recent years.The large area roof falling in the goaf could cause the mine seismic and air dynamic impact occurred.With the analysis and proof the dynamic evolution and space dimension before the mine seismic occurred,the energy conversion and the conservation theory were applied to release the space related dimension of the mine seismic characterization of the goaf and the dynamic impact composed factors.The acoustic emission monitoring and measuring technology was provided as the base and means to predict the mine seismic.The line position method proposed was applied to basic principle of the seismic source positioning.The acoustic emission monitoring and measuring system could be applied to on-line monitor and measure the roof activity above the goaf and could be an effective access to monitor,measure and predict the mine seismic of the goaf.
