Water quality of ground water in Luohe formation and Huanhe formation of Cretaceous system of Binchang mining area have clear change law along horizontal and vertical directions. In the rocks of Huanhe formation, there are gypsum bed, thereby lead content of SO42- increased, and the water quality much poor than Luohe formation. In the Luohe formation,the water quality of recharge area is better than in the drain area. Although the water supply direction of industry and agriculture in the future mining area...

Water quality of ground water in Luohe formation and Huanhe formation of Cretaceous system of Binchang mining area have clear change law along horizontal and vertical directions. In the rocks of Huanhe formation, there are gypsum bed, thereby lead content of SO42- increased, and the water quality much poor than Luohe formation. In the Luohe formation,the water quality of recharge area is better than in the drain area. Although the water supply direction of industry and agriculture in the future mining area may be confined fracture- pore water of Luohe formation in the area,but because of the recharge conditions of ground water of Luohe formation in the area much poor, and the ground water mainly static reserve, so that recoveralbe reserves in the water source district may be limited.

彬长矿区白垩系洛河组、环河组地下水水质在横向上和纵向上的都具有明显的变化规律。由于环河组岩层中含有石膏层,导致SO42-含量增高,水质较洛河组差;洛河组在补给区水质较排泄区好,虽然未来矿区工农业用水的方向可以是本区内洛河组承压裂隙—孔隙水,但由于本区洛河组地下水补给条件较差,地下水以静储量为主,故此水源地可供开采量有限。

A solution to the low gas drainage efficiency for lower-permeability gas-filled coal in China is suggested based on the theoretical analysis and model investigation of the stress-relief moving rules for the roof stratum during working. With this method, the gas is drained from the roof stratum with a strike long-distance drill according to the developing characteristics of the cracks resulting from the stress relief of the mining roof stratum. The contribution of the roof stratum structure and the horizon of...

A solution to the low gas drainage efficiency for lower-permeability gas-filled coal in China is suggested based on the theoretical analysis and model investigation of the stress-relief moving rules for the roof stratum during working. With this method, the gas is drained from the roof stratum with a strike long-distance drill according to the developing characteristics of the cracks resulting from the stress relief of the mining roof stratum. The contribution of the roof stratum structure and the horizon of the key seam to the displacing rules of the roof stratum is analyzed, and the proper zone for the strike long-distance drainage is provided. Judged from the practical experience, the strike long-distance drainage in the roof stratum, with a drainage percentage of 20% for working face, is an ideal method for the coal seam with lower permeability.

针对我国高瓦斯低透气性煤层瓦斯预抽效果差的特点,在分析煤炭回采过程中顶板覆岩卸压移动规律基础上,提出了利用采动煤层顶板覆岩卸压裂隙发育特征,实施覆岩卸压区走向长钻孔抽放瓦斯。实践证明,顶板走向长钻孔覆岩卸压瓦斯抽放是解决低透气煤层瓦斯抽放率低的有效方法,回采面的瓦斯抽放率在20%以上;分析了顶板覆岩结构及关键层层位对覆岩移动规律的影响,给出了顶板走向长钻孔卸压抽放的合理布置区域。
