摘　　要：为科学合理地对大磨岭煤矿副井区域煤层进行突出危险性区域预测及可抽放性评价,对其瓦斯压力、煤的坚固性系数、透气性系数、钻孔瓦斯流量衰减系数、瓦斯放散初速度等瓦斯基础参数进行了测定,根据测定结果及相关规定,确定了本区二1煤层具有煤与瓦斯突出危险性且属于勉强抽放煤层,对副井安全揭穿二1煤层起到了指导作用。In order to scientifically conduct outburst risk prediction and drainage evaluation for regional coal seams at auxiliary shaft of Da Moling Coal Mine, in this paper, basic gas parameters including gas pressure, coal hardness coefficient, permeability coefficient, drilling gas flow attenuation coefficient, gas bleeding initial velocity has been measured and determined. Based on the determination and concerning regu- lations, it comes up with a conclusion that Ⅱ 1 Coal seam of this district possesses coal and gas outburst risks and belongs to the forced drainage level, presenting a guidance role in auxiliary shaft exposing Ⅱ 1 seam.
