丰源煤矿矿井涌水规律及控制因素分析

丰源煤矿位于新疆呼图壁县白杨沟内,井田开采历史较长,存在大量老窑水富集区,且紧邻白杨沟河,故煤矿主井长期面临涌水问题,对主井进行了近两年的排水,涌水量仍未见明显降低,推测主井与白杨沟河、老窑水之间存在较复杂的导水通道。对丰源煤矿及其邻区开展了构造地质调查、水文地球化学分析、地球物理勘探等工作,对矿井突水通道位置和范围变化等情况进行了空间动态连通性分析,基本查明了影响矿井涌水量的主要因素,即:(1)NE向的断层F_4、F_5有一定阻水性;(2)NW向、近EW向节理、断层密集带构成了区域的优势导水结构面;(3)塌陷坑及河道衬砌严重破坏段为拉张塌陷区,构成了地表水和浅层潜水的主要渗漏补给区。

Regularity and Controlling Factors of Mine Inflow in Fengyuan Coal Mine

Fengyuan Coal Mine is located in Baiyanggou,Hutubi County,Xinjiang,with a long mining history,and close to Baiyanggou River.The main shaft of coal mine has been faced with mine Inflow problem for a long time.After draining the main shaft for nearly two years,the mine Inflow has not been significantly reduced.It can be inferred that there are more complex water diversion channels between the main shaft and Baiyanggou River,goaf and fire zone.Based on a large number of tectonic geological survey,hydrogeochemical analysis and geophysical exploration work in Fengyuan Coal Mine and its territory,and combined with the distribution of goaf,burning area,the location and scope of mine Inflow,the spatial dynamic connectivity and spatial mining activation factors are analyzed.The water filling factors,water source composition,water diversion channel and main factors affecting the location and scope of mine Inflow in Fengyuan Coal Mine are basically obtained.
