煤与瓦斯突出大采高煤层采前消突技术研究

Research on Eliminating Ountbust Technology for Coal and Gas Outburst Coal Seam with Large Mining Height

针对阳煤集团寺家庄矿15104工作面的瓦斯赋存具有含量高、压力大、突出危险性大、大采高综采的条件,分析了影响煤与瓦斯突出的主要因素及15104工作面通过走向高抽巷抽采技术、钻孔卸压等技术手段,使煤层瓦斯含量由11.22 m3/t降低到8 m3/t以下,有效降低了煤与瓦斯突出的危险性。

Contrary to the conditions of high gas content,large pressure,big outburst and large mining height and fully-mechanized mining at 15104 face,Sijiazhuang Coal Mine of Yangquan Coal Industry Group Comp,analyses the main factors effecting coal and gas outburst,technology of high drainage,drilling pressure relief at 15104 face and effectively reduces the seam gas content from 11.22 m3/t to 8 m3/t and the coal and gas outburst danger.
