深孔预裂爆破在瓦斯风化带采煤工作面的应用

Deep Hole Presplitting Blasting in Coal Face Using Gas Weathering Zone

淮南矿业集团顾桥矿南区1211(3)采煤工作面位于13槽煤层瓦斯风化带区域,针对其顶板采取相应的深孔爆破措施,文章对瓦斯风化带采煤工作面强制放顶过程进行了研究,对今后采煤工作面顶板欲裂爆破提供了重要的参考依据。

Huainan Mining Group Southern Guqiao Mine Coal Face 1211 （3） positioned in the 13 groove seam gas weathering zone area, take corresponding measures for deep hole blasting in the roof, the paper for gas weathering zone of mining work face forced caving process was studied to provide important reference for the future work of blasting mining face roof.
