兴隆庄煤矿下组煤开采水文地质条件分析及突水防治措施

Analysis of hydrogeological conditions and prediction of water gush for mining lower coal group in Xinglongzhuang coal Mine

分析了兴隆庄煤矿下组煤的水文地质条件及充水因素,利用突水系数法分析了矿区下组煤开采时受十四灰、奥灰水的影响程度。综合考虑矿区内含水层的水文地质特征,根据煤层赋存条件,介绍了兴隆庄煤矿治理突水的方法,研究结果为矿区下组煤开采治理方案的制定及下一步水害防治措施的选择提供了科学依据。

Analyzed the hydrogeological conditions and water filling factors of lower coal group in Xinlongzhuang mine. The influencing degrees that Gray 14 and Ordovician limestone on the exploitation of lower coal group is analysed using the method of water bursting coefficient. Synthetically considering the hydrogeological conditions of coalfield aquifer, introduced the prevention and control measures of water bursting, provide the foundation for controlling the aquifer water for mining lower coal group.
