煤矿底板突水微震监测预警系统构建与分析
|
摘要
为了有效遏制煤矿突水灾害对矿井安全生产带来的严重影响,寻找诱发煤矿突水的本质机理和微破裂前兆规律,进而对煤矿突水灾害进行分析预报;采用微震监测技术,结合董家河煤矿水文地质情况,建立微震监测系统;对董家河煤矿22517工作面底板进行微震监测分析,得到了通过微震监测结合地质钻孔柱状综合分析确定底板破坏深度的方法。微震监测结果表明:底板微震事件主要分布于3个区域;董家河煤矿22517工作面底板的总体趋势趋于稳定,但局部可能发生损伤,从而使局部岩体的渗透系数增加,形成底板出水点,该出水点可能位于工作面前方50 m至后方30 m区域。
To effectively curb the serious impact of coal mining water inrush disasters on mine safety production, seeking the intrinsic mechanism of inducing water inrush from coal mines and the law of micro-cracking, and then analyzing and predicting coal mining water inrush disasters, microseismic monitoring technology was combined with the hydrogeological conditions of Dongjiahe Coal Mine to establish a microseismic monitoring system. Microseismic monitoring was performed on the floor of 22517 working face in Dongjiahe Coal Mine, and a method of determining the floor destruction depth through microseismic monitoring and columnar comprehensive analysis of geological drilling was obtained. Microseismic monitoring results show that the microseismic events are mainly distributed in three regions. The overall trend of the floor of the 22517 working face of Dongjiahe Coal Mine is stable, but the local damage may occur, so that the permeability coefficient of the local rock mass is increased to form the floor water outlet point, which may be located between 50 m in front and 30 m behind the working face.
