摘要
通过对钻屑解吸指标Δｈａ、吸附平衡瓦斯压力Ｐ、瓦斯放散初速度ΔＰ、煤的坚固性系数ｆ值和煤的挥发份Ｖ的测定，建立了Δｈ２同参数Ｐ、Ｋ的关系。
ased on the measurements of gas desorption index of drillings,Δh 2,gas pressure at absorption balance,p,initial velocity of gas emission,ΔP,Protodyakonov coefficient of rock strength,f,and volatile matter of coal,V,the relationship between Δh 2 and P,K,was established,thus a series of methods were proposed to determine the critical value of Gas desorption index of drillings,Δh 2.
