摘要：North China-type coal field of deep coal seam mining in Shanxi formation often faces the threat of roof water inrush. In order to reduce or avoid the roof water disasters, on-site technical personnel usually carry out the release of roof water through the roadway drilling based on the electric prospecting data obtained before the working stope mining. In fact, it is difficult to effectively release roof water in sandstone aquifers before coal seam mining since the connectivity between roof aquifers is very poor. In order to solve this problem, taking Shandong Xinjulong Energy Co., LTD. the first mining face No. 1301N working stope as practice research background, we put forward to effectively release the roof water with roadway drilling according to the three-dimensional high-density resistivity method detection results during the process of working stope mining, because the roof strata can be destroyed under the action of ground pressure, which makes the hydraulic relationship between roof aquifers better. The results show that three-dimensional high-density resistivity method is reliable for roof water advanced detection during working stope mining, which can effectively guide the roof water in sandstone to be released through roadway drilling. Therefore, the safety mining of the first mining face No. 1301N working stope is ensured.
