摘要
为加强煤矿防治水工作,防止和减少水害事故,需进行矿井涌水量预测计算。以园子沟煤矿为例,考虑地表水、含(隔)水层、地下水补给、径流及排泄条件等地质特征,结合矿井充水水源及充水通道分析,运用大井法、集水廊道法和比拟法对矿井涌水量进行了计算,通过经验公式和比拟法确定了离层水突(涌)水量。发现大井法和集水廊道法计算结果偏小,水文地质比拟法是根据相邻矿井生产情况并结合自身水文地质条件预测涌水量,较为符合实际;预测矿井正常涌水量164 m^3/h,最大涌水量为214 m^3/h;预测了1012001工作面如发生离层水突水事故,正常涌水量1 340 m^3/h,最大涌水量2 300 m^3/h,累计最大出水量为54 878 m^3。
In order to strengthen the prevention and control of water in coal mines and reduce water disaster accidents,it is necessary to calculate and predict the mine water inflow.Taking Yuanzigou coal mine as an example,considering the geological characteristics of surface water,aquifer,groundwater recharge,runoff and drainage conditions,combined with the analysis of mine water-filling source and water-filling channel,the mine water inflow was calculated by using big well method,catchment corridor method and analogy method,and the water inflow from separated layer was determined by empirical formula and analogy method.The comparison shows that the calculation results of big well method and catchment corridor method are on the small side,and the results of hydrogeological analogy method are more in line with the reality.Finally,the normal mine water inflow is predicted to be 164 m^3/h,and the maximum mine water inflow is 214 m^3/h.If water inrush accident occurs in No.1012001 working face,the normal water inflow is 1 340 m^3/h,the maximum water inflow is 2 300 m^3/h,and the cumulative maximum water inflow is 54 878 m^3.
