In view of the dangers of accumulated water in the upper goafs to mining of the lower coal seam in the binary coal seam, it was proposed to drill exploration and drainage holes, plus large diameter pumping wells from surface through the upper multiple goaf areas for water discharge. The application of the process to treat the accumulated water in the Jurassic goaf in the Datong mining area indicated that the exploration and drainage hole can effectively drain water from the goaf to the lower Carboniferous coal seam roadway; while the large diameter pumping well can achieve discharge of the goaf at large flows. A total of 3.981 million m3 of accumulated water in the goaf was drained by the 9 exploration and drainage wells, and more than 2 million cubic meters of accumulated water in the goaf discharged by the 5 large-diameter pumping wells, achieving good drainage results. This paper introduces the application of the exploration and drain well, and large-diameter pumping well drilling processes to the water control of the Jurassic goaf in the Tongmei Group Tongxin Mine, providing reference for the goaf water drainage in the similar mining condition.
