超前瞬变电磁探测技术研究及工程实践

为解决安达煤业掘进过程中顶板水和断层水对工作面造成的威胁,根据+1070m疏放水联巷的水文地质概况及现场掘进情况,采用超前瞬变电磁探测技术,对煤层顶板水进行超前探测.结果 表明:工作面前方有低阻异常区,使用超前探孔技术探放顶板水是可行的,可以排除工作面前方的水害隐患,同时为煤层的安全开采提供依据.

Research and Practice of Advanced Electromagnetic Detection Technology

In order to solve the threat of roof water and fault water to the working face in the excavation process of Anda Coal Industry,according to the hydrogeological situation of + 1070 m drainage combined roadway and the on-site excavation situation,the advanced transient electromagnetic detection technology is adopted to detect the coal seam roof water in advance.The results show that there is an abnormal area of low resistance in front of the working face,and it is feasible to use the advanced exploratory hole technology to detect and release the roof water,which can eliminate the hidden danger of water disaster in front of the working face,and provide a basis for the safe mining of coal seam.
