摘要
石门揭穿急倾斜突出煤层是一项技术性十分繁复的工作。通过各项措施减少瓦斯压力和地应力,消除诱发突出因素,采用煤体固化技术增强围岩、煤体强度,严格执行安全防护措施,可以防止石门揭煤突出事故。
Steep outburst seam while crosscutting is a complex technical work. Gas pressure and crustal stress can be crippled, and the outburst factor can be eliminated by using varies of measures to reduce gas press and ground stress. Crosscutting outburst accidents can be prevented by using coal solidifying technology to strengthen wall rock and coal intensity.
