摘 要:为了提高万年矿矿井产量,降低矿井奥灰突水威胁,主要从分析万年矿与相邻南洺河铁矿的开采关系入手,着重研究万年矿井田范围内奥灰水补给特点以及地下水动态流向特征,确定万年矿为独立水文地质单元,证实了万年矿区与周边区域水文地质富水条件呈“外弱内强”的特点。通过南洺河铁矿的疏排奥灰水以控制万年矿井下奥灰水的疏降,提出了以南洺河铁矿为中心的区域内整体呈“漏斗式”沉降的观点,保证了万年矿-150 m以浅的下组煤开采的安全性。结果表明,降低矿井奥灰水的突水威胁后,矿井产出下组煤将带来巨大的经济效益,也杜绝了资源的浪费。In order to improve the production of Wannian Mine and reduce the threat of limestone sudden water in the mine,the mining relationship between Wannian Mine and the neighboring Nanluanhe Mine was studied,the characteristics of ash water recharge and the dynamic flow of groundwater within the mine field of Wannian mine were focused,Wannian mine was taken as an independent hydrogeological unit,and confirming that the hydrogeological water-rich conditions of Wannian mine and the surrounding area are"weak outside and strong inside"characteristics.The Nanminghe iron ore mine's evacuation ash water evacuation was adopted to control the Wannian Mine underground ash water evacuation,the iron ore mine as the overall funnel sinking point center of the region was given,which ensured the safety of the Wannian Mine-150 m shallow lower group coal mining.The results showed that after reducing the threat of sudden water of ash water in the mine,the mine output of lower group coal would bring great economic benefits,and also eliminate the waste of resources.
