综放工作面“以孔代巷”瓦斯治理技术应用

Application of “Replace Roadway with Hole” Gas Treatment Technology in Fully Mechanized Caving Face

针对王家岭矿采煤工作面“厚煤层、高产量、瓦斯低含量”的特点,拟定采用顶板走向长钻孔代替高抽巷的瓦斯治理技术。以该矿18103工作面为工程实例,通过施工定向顶板走向长钻孔进行抽采试验,以验证“以孔代巷”瓦斯治理的可行性及有效性,应用取得显著效果。

In response to the characteristics of "thick coal seams,high production,and low gas content" in the coal mining face of Wangjialing Colliery,gas control technology of using long boreholes along the roof instead of high drainage tunnels has been proposed in the paper.Taking the 18103 working face of the mine as an engineering example,the feasibility and effectiveness of "Replace roadways with holes" gas control have been verified through directional roof strike long drilling and extraction tests,which achieves significant application results.
