【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。
[Abstract]:Based on the analysis of the comprehensive action hypothesis, the criterion of coal and gas outburst is further simplified, the distribution model of gas pressure in coal roadway driving is established, and the problem of gas outburst direction angle in coal roadway tunneling is explained. The paper designs the plan of drilling and drilling ahead of the floor, and controls the gas outburst disaster in the roadway driving of section 鈪，
