新集煤矿1#煤开采底板突水可能性分析

An analysis of the possibility of water inrush from carbonic limestone during the 1# coal seam mining in the Xinji coal mine

摘要: 新集煤矿1#煤层储量大、煤质好,对其进行开采是稳定和扩大产量、提供优质煤炭资源的保障。开采1#煤层遇到的最主要威胁是下伏太灰承压水突出。文章在分析淮南煤田和新集煤矿水文地质条件的基础上,对新集煤矿太灰岩富水性、底板岩层隔水能力以及构造控水特征等进行初步研究,判断1#煤开采过程中太灰水突出的危险性,分析可能的防治措施,为安全、高效开采1#煤层提供前期研究成果。

Abstract: The 1# coal seam in the Xinji coal mine is of large storage capacity and of nice coal quality.Exploiting the 1# coal seam can stabilize and enlarge the volume of coal production and can supply coal resources of good quality.The most important threat is water bursting out from the underlying carbonic limestone.This paper introduced the hydrogeologic conditions of the Huainan coalfield and the Xinji coal mine,studied the water content of carbonic limestone,the impermeable ability of 1# coal seam f...
