通过钻探手段揭露了郭庄煤矿17煤开采直接充水含水层14灰和奥灰,掌握17煤到14灰和奥灰的间距、岩性以及隔水岩组赋存状态和隔水性能,获取14灰和奥灰的相关水文地质参数,揭示了其漏水规律,并根据获取的资料利用突水系数理论,分析14灰水和奥灰水对17煤安全开采的影响,提出了17煤安全开采建议采取的防治水措施,为矿井安全生产提供依据和参考。
Through drilling, the results show that the coal-bearing aquifer 14 and the ashes of 17 coal mining in Guozhuang Coal Mine have been mastered, and the distance and lithology of 17 coal to 14 ashes and the ashes, and the occurrence state and water-proofing property of the water- According to the obtained data, the water inrush coefficient theory is used to analyze the influence of 14 gray water and Ordovician gray water on the safe mining of 17 coal, and the 17 coal safety mining is put forward Proposed measures to prevent and control water supply for mine safety basis and reference.
