通合煤矿2105工作面顶板水探查与疏放技术研究

Research on roof water exploration and drainage technology of No.2105 Face in Tonghe Coal Mine

为精准防治通合煤矿2105工作面顶板水害,采用并行电法探测技术对煤层顶板进行了探查,共计圈定4个异常区,分别为上顺槽通尺0~130 m异常区,下顺槽通尺0~63 m、通尺360~603 m以及通尺870~905 m异常区,在此基础上采用定向钻孔探查技术探查了异常区的富水性,并进行了疏放,实现了工作面的安全开采,为矿井后续工作面以及相似地质条件矿井的安全开采提供了经验借鉴。

In order to accurately prevent and control the roof water disaster of No.2105 Face in Tonghe Coal Mine,the parallel electrical method was used to detect the roof of the coal seam.A total of 4 abnormal areas were delineated,which were 0~130 m abnormal area of the upper crossheading,0~63 m,360~603 m and 870~905 m abnormal areas of the lower crossheading.On this basis,the directional drilling exploration technology was used to detect the water abundance of the abnormal area,and the drainage was carried out to realize the safe mining of the working face,which provided experience for the safe mining of the follow-up working face of the mine and the mines with similar geological conditions.
