摘要
基于平顶山六矿外口水库和丁二下山采区的地质采矿条件 ,分析了水库所压的丁 5- 6 煤层开采前后地层中是否存在突水通道 ,涉及地质构造、地层中隔水层和与矿井涌水量相关的因素 ,计算并类比了开采形成的导水裂缝高度和水体下开采的安全深度 。
Based on the Waikou reservoir and geological and mining condition of the second dip district from J group of seams,in the sixth mine of Pingdingshan mining area,it is analyzed whether flooding passages or channels exist in strata,before and after J5-6 coal seam is extracted under the reservoir,which involve geological structures,water partition layers and relative factors to concern mine inflow,the height of fracture zone conducted water and safe mining depth are calculated and drawn a analogy,the feasibility for safe mining under the reservoir is demonstrated.
