河南先锋煤业水文地质特征分析

摘要

通过对河南先锋煤业矿井、地质构造及水文地质条件分析,结合二1煤层直接充水含水层 ——太原组上段灰岩含水层的水文地质特征,本文确定了先锋煤业矿井主要充水水源及主要充水通道,评价了先锋煤业矿井突水危险性.通过对矿井充水水源及充水通道的分析计算,划定了对矿井威胁较大的充水因素,为矿井深部开采防治水工作提出了可行建议.%Through the analysis of the geological structure and hydrogeological conditions of Henan Xianfeng coal mine and the hydrogeolo, and the combination of Taiyuan formation in limestone aquifer hydrogeological characteristics, this paper determines the Xianfeng coal mine water filling source and channel, and evaluates the water inrush risk of Xianfeng coal mine. Based on the analysis and calculation of the water supply and water filling channel of the mine, the water filling factor of the mine threat is determined, and feasible suggestions are put forward for the prevention and control of water in the deep mining area.
