摘要: 以MT/T1037-2007为依据,采用煤层残余瓦斯压力指标对吉克煤矿首采工作面消突措施效果进行了评价, 并辅以工作面瓦斯抽排率进行验证,结果表明,区域预抽煤层瓦斯防突措施有效。Abstract: Bases on MT/T1037-2007, the paper uses the method of seam residual gas pressure index to evaluate the effect of outburst prevention measures for first coal mining face in Jike Coal Mine, and adds the method of gas pumping-exhaust rate to verify the conclusion. The result shows that the prevention measure of regional pre-drainage gas for coal seam outburst are effective.
