根据葛泉矿1192工作面的实际情况,利用应力应变观测和注水试验对工作面底板的最大破坏深度进行探测。结合葛泉矿水文地质条件分析结果及底板探测结果,利用突水系数法对工作面底板的突水危险性进行分析,为葛泉矿9#煤的安全开采提供科学依据。
According to the actual situation of 1192 working face of Gequan Mine, the maximum destructive depth of the floor of the working face is probed with stress-strain observation and water injection test. Based on the analysis results of geologic conditions of gequan quarry and the detection results of floor, the water inrush coefficient method is used to analyze the danger of water inrush from the work face and to provide a scientific basis for safe mining of 9 # coal in gequan mine.
