摘要
通过测定大兴矿的突出预测参数，建立了钻屑解吸指标同瓦斯压力、瓦斯放散初速度指标、煤的普氏系数和煤的挥发分之间的关系，进一步得出了适合大兴矿七煤层的钻屑解吸指标临界值。
Detecting the coal and gas outburst prediction parameters for Daxing Coal Mine,established lndexes of drill cuttings absorption and release,gas pressure and inital release speed,the relationship between the protodyakonov coefficents and coal volatile matter.Obtained drill critical values of cuttings proper indexes for No.7 seam in Daxing Coal Mine.
