摘要
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,by borehole televiewer system and borehole flushing fluid leakage,the height of water flowing fractured zone of overburden,deep buried,extra thick coal seam and fully-mechanized caving mining is monitoring. The digital analysis, similarity simulation and numerical simulation experiment of fissure development evolution are carried out.
