牛儿庄矿带压开采深部6~#煤可行性研究

Feasibility research on mining under safe waterpressure of aquifer of No.6 Coal in the deep of Niuerzhuang Coalmine

通过对牛儿庄矿56805工作面水文地质条件的分析及注水试验对工作面底板的最大破坏深度的探测,研究工作面底板隔水层阻水性能,采用突水系数法对56805工作面开采的可行性进行分析。结果表明56805工作面具备带压开采的基本条件,为牛儿庄矿实现安全带压开采深部6#煤提供科学依据。

Based on the analysis of hydrogeologic conditions of 56805 Working Face of Niuerzhuang coalmine, probed the maximum failure depth of the working face floor using the water injection test, and researched the water resistance performance of water-resisting floor,analyzed the mining feasibility of56805 Working Face by inrush coefficient method. The results showed that 56805 Working Face has the basic conditions for mining under high pressure, which provided scientific basis for mining under safe waterpressure of aquifer of No.6 Coal in the deep of Niuerzhuang Coalmine.
