太行山东麓矿井水文地质条件及充水因素分析——以奇胜煤矿为例

Analysis on Hydro-geological Conditions and Water Filling Factors of the Mine at the Eastern Foot of Taihang Mountain——a Case Study of Qisheng Coal Mine

水害为煤矿开采过程中重要灾害之一。奇胜煤矿主要开采2号煤层,根据主采煤层赋存分布特征,以矿区水文地质条件为基础,充分分析矿井水充水水源(含水层水和老空积水)、充水通道(导水断层、开采裂隙),并预测了矿井最大涌水量(30m^(3)/h)。在煤矿开采过程中,充分了解矿井灾害,是保护人员财产安全的必要基础。本次矿井水文地质条件及充水因素分析,为太行山东麓一带矿井水害防治,提供了参考依据。

Water disaster is one of the most important disasters in coal mining.2#coal seam is mainly mined in Qisheng Coal Mine.According to the occurrence and distribution characteristics of the main coal seam and based on the hydro-geological conditions of the mining area,the source of mine water filling water(aquifer water and goaf water)and the water filling channel(water-conducting fault and mining fissure)are fully analyzed,and the maximum water inflow(30m^(3)/h)of the mine is predicted.In the process of coal mining,fully understanding the mine disaster is the necessary basis to protect the safety of personnel and property.The analysis of mine hydro-geological conditions and water filling factors provides a reference for mine water disaster prevention and control at the eastern foot of Taihang Mountain.
