摘　　要：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。Niangmutie coal mine is located in the Qinghai-Tibet plaieau years tundra, and melting of permafrost region, made of mine hydrogeology has source and filling channel, analyzed the filling analogue method to predict the flow of water prediction results show that the mine water sources are mainly sandstone fissure water; its particularity, combined with the mine water filling water of the mine,and using big well method and in the first mining area of the mine. The analysis and filling channel is all kinds of melting zone and water filling the flow of water in the first mining area of the mine is low, provided an important basis for the design of the mine exploitation.
