摘要
煤矿水害一直是影响煤矿生产安全的重要因素,陕西禾章沟煤矿为保证工作面开采安全,开采前须查明顶板岩层的富水情况,此次采用音频电透视法对回采工作面顶板进行探查,根据音频电透视法勘探成果,结合相关地质资料,综合分析与评价该工作面顶板岩层富水情况,为该工作面安全回采提供技术依据,以保障煤矿安全生产。
Water damage in mines has always been an important factor affecting the safety of coal mine production,in order to ensure the mining safety of a mine in Shaanxi,the water-rich situation of the roof rock layer must be identified before mining the working face.The technical basis was provided for the safe recovery of the working face to ensure the safe mining.
