摘要
高瓦斯突出矿井采用高位抽放巷预抽煤巷瓦斯,结合煤巷巷帮迈步钻场内施工大孔径长钻孔"边抽边掘",是采煤工作面顺槽煤层快速降低瓦斯含量,消除突出危险性的有效手段,该技术在五轮山煤矿煤巷掘进中得到了较好的应用。
The paper introduces the technology of pre--draining through high--level suction tunnels and＂ draining while driving＂ by drilling large aperture and long holes in mobile drilling field, which can reduce gas content rap- idly in crossheadinz seam and control outburst effectively in Wulunshan Colliery.
