挖金湾煤业矿井涌水量及影响因素分析

Analysis of Mine Water Inflow and Influencing Factors in Wajinwan Coal Industry

针对挖金湾煤业8115工作面4号煤层开采中的涌水量进行计算及影响因素进行分析,旨在为防突水措施的制定提供依据。分别采用对比测算法和动力学计算法计算了矿区涌水量,正常涌水量为3.77 m3/h,最大约为5.11 m3/h。结合矿区实际,分析了断层结构、含水层、采空区积水以及奥灰水对涌水量的影响机理和程度。

The article calculates the water inflow during the mining of the No.4 coal seam at the 8115 working face of the Wajinwan Coal Industry and analyzes its influencing factors.Using the comparative measurement algorithm and the dynamic calculation method,it is concluded that the normal water inflow in the mining area is 3.77 m3/h,and the maximum is about 5.11 m3/h.Combining the actual situation of the mining area,the article also analyzes the mechanism and extent of the influence of fault structure,aquifer,water in the goaf,and Ordovician lime water on the water inflow,which provides a basis for the formulation of anti-water inrush measures.
