娘姆特煤矿地处青藏高原多年冻土带,多年冻土和融区的存在,矿井水文地质有其特殊性,结合矿井充水水源和充水通道分析了矿区充水因素,并运用大井法和比拟法预测了矿井首采区的涌水量。分析和预测结果表明:娘姆特矿井的主要充水通道是各种融区,主要充水水源为砂岩裂隙水,且矿区首采区涌水量较低,从而为矿井的设计、开采提供了重要依据。
Nimu special coal mine is located in the permafrost zone, permafrost and melting zone of the Qinghai-Tibet Plateau, the mine hydrogeology has its own particularity, combined with mine water and water-filled channels to analyze the water filling factors, and the use of a large well method And comparative method to predict the first mining area of the mine water inflow. The results of analysis and prediction show that the main waterflooding channels in the Namt mine are all kinds of financial zones, and the main source of water for filling is sand fissure water, and the water inflow in the first mining area is relatively low, which provides important for the design and mining of mines in accordance with.
