奥灰水是鲍店煤矿石炭系太原组下组煤开采的主要水害威胁和重点防治对象。在水文地质勘探和深入分析、研究水文地质条件基础上,推荐了下组煤首采区位置,并精细模拟了鲍店煤矿下组煤首采区奥灰疏降水量。模拟结果为:奥灰最大疏降水量为540m~3/h,降至安全水头的时间约30d。综合分析认为,该疏降水量符合模拟区的实际水文地质条件,该疏降水量可以作为下组煤开采水平或采区防排水能力设计的依据。
Ordovician gray water is the main threat to water hazards and key prevention and control targets of coal mining in the Lower Carboniferous Taiyuan Formation of Baodian Coal Mine. On the basis of hydrogeological exploration and in-depth analysis and research of hydrogeological conditions, the location of the first coal mining area of the lower coal group is recommended and the amount of gray scale dewfall in the first coal mining area of Baodian Coal Mine is carefully simulated. The simulation results show that the maximum de-anhui precipitation is 540m ~ 3 / h and the safety time is about 30 days. The comprehensive analysis shows that the amount of dewatering is in line with the actual hydrogeological conditions of the simulated area, and the amount of dewatering can be used as the basis for designing the coal mining level or the drainage and drainage capacity of the mining area.
