店坪煤矿充水条件分析及涌水量预测研究

Analysis of water filling condition and prediction of water inflow in Dianping Mine

矿井充水因素、涌水量对于水害防治措施的设计与实施具有重要的导向作用,因此充水水源、涌水通道、涌水量的研究分析对矿井排水系统设计、安全生产具有重大意义。以店坪煤矿为研究对象,对该矿主要可采煤层的充水因素进行研究分析,运用比拟法、大井法对5、9、10号主要煤层开采期间矿井涌水量进行预算,为水害防治提供基础数据支撑。

Mine water filling factors and water inflow play an important guiding role in the design and implementation of water damage prevention and control measures.Therefore,the research and analysis of water filling source,water inflow channel and water inflow are of great significance to the design of mine drainage system and safe production.Taking Dianping mine as the research object,the water filling factors of main minable coal seams in the mine were studied and analyzed.The analogy method and large well method were used to predict the mine water inflow during the mining of No.5,9 and 10 main coal seams,which provided basic data support for water damage prevention and control.
