长榆河煤业充水因素分析及涌水量预测

Analysis on Water-filling Factors and Prediction of Water Inflow Amount in Changyuhe Coal Industry Co., Ltd.

矿井涌水量是评价矿井水文地质条件复杂程度的重要指标,同时充水因素的确定对于水害防治措施的实施有着目标导向的作用,因此,分析充水因素和正确预测矿井涌水量对于指导矿井排水设施建设、消除水害威胁、保障煤矿安全生产具有重要意义。对长榆河煤业开采15#煤层、15下#煤层时的充水因素进行了分析,并选用大井法和富水系数比拟法对矿井涌水量进行了预测,最终结合实际,得出了矿井涌水量,为水害防治提供基础数据支撑。

Mine water inflow amount is an important indicator for evaluating the complexity of mine hydrogeological conditions.At the same time,the determination of water-filling factors has a goal-oriented effect on the implementation of water disaster prevention and control measures.Therefore,analyzing water-filling factors and correctly predicting mine water inflow amount is of great significance for guiding the construction of mine drainage facilities,eliminating the threat of water hazards and ensuring work safety in coal mines.This paper analyzed the water-filling factors in mining 15#coal seam and 15lower#coal seam of Changyuhe Coal Industry Co.,Ltd.,selected the large well method and the rich water coefficient comparison method to predict the mine water inflow amount,and finally obtained the mine water inflow amount combined with the actual situation,which can provide basic data support for the prevention and control of water hazards.
