摘 要:通过对新集二矿6#、13#煤层瓦斯压力的测定,分析了煤层瓦斯压力的分布规律,根据瓦斯压力的分布规律,划分出新集二矿6#和13#煤层各自在标高-600~-550 m范围内的突出危险区和无突出危险区。并结合煤的破坏类型、瓦斯散放初速度和煤的坚固性系数三项指标,验证了突出危险区的划分效果,结果显示,单项指标与瓦斯压力的分布规律相符合。Through measured the gas pressure of No. 6 and No. 13 coal seam in Xinji No. 2 coal mine, the gas pressure distribution law of the coal seams was analyzed. And according to the gas pressure distribution law, the out-burst dangerous zones were divided of No. 6 and No. 13 coal seam in level -600 - -550 m. Combines with three indexes of the coal damage types, initial speed of methane diffusion and firmness coefficient of coal, the effect of the zone division about outburst dangerous was verified. The result shows that the single index method is consistent with the gas pressure distribution.
