摘要
通过对综合作用假说解析的基础上,进一步简化了煤与瓦斯突出判据;建立了煤巷掘进时瓦斯压力分布模型,解释了煤巷掘进时瓦斯突出方向角问题;设计了底板穿层钻孔和超前钻孔方案,控制芦岭煤矿Ⅱ829区段煤巷掘进时瓦斯突出灾害,经检验,设计方案取得了良好的效果。
The criteria of coal and gas outburst is symplified based on the analysis of the combination mechanism of hypothesis.The problem about the direction of outburst is solved via building a model of. the gas pressure distribution. Designed and tested an project for Luling coal mine Ⅱ 829 to prevent outburst during coal roadway tunneling, in which bottom wear layer drilling and advanced borehole is used , of which the result is good.
