煤矿井充水特征及多方法预测矿坑涌水量

评价矿井充水特征和预测矿井涌水量是煤矿床水文地质勘查中一项重要和复杂的工作,不同矿区呈现出不同的水文地质特征,单方法预测矿坑涌水量风险较大,与实际出入甚远,应深入分析水文地质条件和矿床充水的各项因子,采用多方法预测矿坑涌水量。以云南省镇雄县坪上兴隆煤矿为例,分析研究水文地质条件和矿井充水特征,分别采用比拟法、地下水动力学法和回归分析法预测矿坑涌水量,为兴隆煤矿提供安全生产参考,也为矿区水资源开发和水环境保护提供依据。

Water Wells Filling Characteristics and Mine Water Bursting byMore Methods Prediction

The evaluation of mine water filling characteristics and prediction of mine water inflow is an important and complex work in coal mines in different mining area hydrogeological exploration,presents the hydrogeological characteristics of different,single method in the prediction of water inflow of mine risk,very far and the actual entry,the factor analysis of the hydrogeological conditions and ore deposits water,the method for prediction of water inflow of mine. Taking Zhenxiong County of Yunnan Province Ping Xinglong coal mine as an example,analysis of the hydrogeological conditions and mine water filling characteristics,respectively,by analogy,prediction of water yield of mine groundwater dynamics analysis method and regression method,provide reference for Xinglong coal mine safety production,but also for the mine water resources development and water environment protection.
