以彬长矿区某矿为试验矿井,采用钻孔电视系统和冲洗液消耗量观测法,对深埋特厚煤层综放开采覆岩导水裂隙带发育规律进行探测,并对采动覆岩裂隙动态演化特征进行数字化分析和相似材料模拟试验研究。
Taking a mine in Binchang mining area as the experimental mine, the drilling TV system and the flushing fluid consumption observation method were used to detect the development rule of overlying rock hydraulic fractured zone in fully mechanized top coal caving mining of deep and extra-thick seam, Dynamic evolution characteristics of digital analysis and similar materials simulation test.
