摘要
以开滦矿区范各庄矿12#煤层导水断层导通奥灰水层为例,采用《矿井水文地质规程》和F-RFPA2D软件分别计算了断层防水煤柱留设。结果表明,《规程》和F-RFPA2D计算结果有一定的差异性,《规程》计算结果偏大,为138.56 m,计算方法简单易掌握。F-RFPA2D计算防水煤柱的结果更容易结合煤层开采的地质实际开展,先开采断层上盘防水煤柱预留为80 m,开采断层下盘防水煤柱预留为100 m。
Taking No.12 coal seam of Fangezhuang in Kailuan mining area as an example,the setting of fault waterproof coal pillar is calculated by using"mine hydrogeology regulation"and F-RFPA2 D software.The results show that there are some differences between the calculation results of"regulation"and F-RFPA2 D.The calculation resultsof"regulation"arelarge,138.56 m,and the calculation method is simple and easy to grasp.F-RFPA2 D calculation result of waterproof coal pillar is more easily combined with the geological practice of coal seam mining,first reserve the waterproof coal pillar of the upper wall of the fault for 80 m,and reserve the waterproof coal pillar of the lower wall of the fault for 100 m.
