摘要
由于彬长矿区水帘洞矿采煤工艺等问题,导致采空区分布不规律且无详细水文地质资料,严重威胁了煤矿高效安全生产.为了精准探查煤矿采空区的分布规律,避免灾害事故的发生,采用孔中雷达、孔中窥视、轨迹测量及孔间无线电波透视与常规直流电测深法相结合的方式进行探测,利用孔中物探勾画出采空区的边界,结合直流电测深对采空区的反映规律及钻孔揭露情况,圈定出5处采空区,为煤矿安全开采提供有力依据.
Abstract
Due to the problems of coal mining technology in Shuiliandong Mine in Binchang mining area,the distribution of goaf is irregular and there is no detailed hydrogeological data,which seriously threatens the efficient and safe production of the mine.In order to accurately explore the distribution law of coal mine goaf and avoid the occurrence of disasters and accidents,the combination of hole radar,peep in hole,trajectory measurement,radio wave perspective between holes and conventional direct current method exploring depth was used for detection.The boundary of goaf was delineated by geophysical prospecting in hole,and five goafs were delineated by combining the reflection law of direct current method exploring depth on goaf and the exposure of drilling holes,which provided a strong basis for coal mine safety mining.
