【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。从而提出了一套确定钻屑解吸指标Δｈ２临界值的方法更多还原

【Abstract】 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.更多还原
