摘要
针对斜沟煤矿8号煤层18102工作面的地质特征,进行现场钻孔压水试验.并用井下实测结果,提出合理综采一次采全高条件下"三带"高度计算的经验公式,对采区和工作面防水煤柱的留设、一次采全高的留采比确定具有一定指导意义。
Based on the geological features of 18102 working face in No.8 seam in Xiegou Mine, the drilling water pressure experiment was conducted in the field. On the field observation results, the paper proposed the empirical formula for three-zone height calculation in the condition of large-mining-height mining and determined the setting of water-proof pillars in mining area and the setting-mining ratio.
