露天煤矿的充水因素分析及涌水量预测

Analysis of water-filling factors and prediction of water inflow in surface coal mines

矿坑涌水是威胁矿区安全生产的重大隐患。本文以新疆后峡煤田某露天煤矿为例,研究矿区的地质及水文地质条件,进行充水因素分析,采用勘探阶段的水文孔资料以及矿井近年的生产资料确定计算参数值,针对性的选用比拟法和大井法进行矿坑涌水量的预测,并对计算结果进行了对比分析。所得出的结果为矿井生产和设计提供了重要依据,对其他矿井的涌水量预测也有一定的参考意义。

Mine gushing water is the major risk of mining production safety hazards.Take a surface coal mine in xinjiang houxia coalfield for example,this paper studies the geological and hydrogeological conditions of the mining area,analyzes the filling factors of the mine.Using the hydrological hole data of the exploration stage and the production data of the mine in recent years to determine the calculated parameter value,analogue method and the big well method are used to predict the inflow of water.Then compare and analyze the results.The results provide an important basis for mine production and design.It is also useful for the prediction of the water inflow of other mines.
