摘要
Abstract
The 22301 face is the first mining face of the third panel in Daliuta Mine and the upper is the goaf of 12301 face.By researching and estimating,the goaf water quantity is about 2.285 million m3 which is a huge security risk to the mining of 22301 face.By operating drillings using XY-2 mine drill in goaf floor,the goaf water was discharged.The detecting shows that the goaf water level has significantly decreased and the goaf water was discharged successfully.关键词
