摘要
通过对突出矿井的突出煤层的考察,结合有关研究结论,煤层突出危险性的瓦斯压力pmin临界值不仅与煤的坚固性系数f和煤的挥发分V有关,而且与煤层的瓦斯放散初速度Δp有关,找出了它们之间的关系式,对确定不同突出煤层发生突出的瓦斯压力临界值并针对性的防止煤与瓦斯突出具有积极的指导意义。
Through the investigation of outburst coal seam in outburst mine, combined with relevant research conclusions, the critical value of gas pressure pmin of coal seam outburst is related not only to the coefficient f of coal solidity and the volatile matter V of coal. Moreover, it is related to the initial velocity of gas release Ap of coal seam. The relationship between them is found out, and the critical value of gas pressure of different outburst coal seam is determined. Prevention of coal and gas outburst has positive guiding significance.
