针对下峪口煤矿深部二水平近水平中近距离2~#、3~#煤层群的煤与瓦斯突出灾害特征与规律,按照先区域、后局部的综合防治煤与瓦斯动力灾害防治技术体系在2~#煤层进行了试验,采用了适合该矿条件的突出预测敏感指标体系,并初步确定了突出预测敏感指标临界值。之后使用该指标在下峪口煤矿的扩大验证区域进行试验验证。
Aiming at the characteristics and regularities of coal and gas outburst disasters in 2 ~ # and 3 ~ # coal seams near the level 2 in the deep level of Xiayukou Coal Mine, according to the comprehensive prevention and control technology system of coal and gas dynamic disasters in the first area and the latter part, 2 ~ # coal seam were tested, and the forecasting index system which is suitable for this mine condition was adopted, and the critical value of the predictor of sensitivity index was preliminarily determined. Afterwards, the indicator was used to test the area under the expansion of Xiayikou coal mine.
