摘要
针对平顶山十二矿己15煤层具有突出和冲击地压双重危险条件,采用钻屑量S、钻孔瓦斯涌出初速度q和瓦斯涌出衰减系数cq等指标进行煤巷掘进动力灾害预测研究,得出合理的敏感指标及其临界值,该项研究对矿井安全生产起到了重要的指导作用。
To counter the double dangers of outburst and rock burst possessed by the 6th Coal Seam in Pingdingshan No. 12 Mine, prediction research on the dynamic disaster during coal roadway drivage was conducted according to the indexes including the drill cuttings S, the initial velocity of gas emission from borehole q, the attenuation coefficient of gas emission cq and so on, and rational sensitivity index and its critical value were obtained. This research played an important guiding role for safe production in coal mine.
