摘　　要：根据瓦斯解吸指标K_1值的测定原理及现场测定方法,对山脚树煤矿的24#煤层进行了K_1与煤层坚固性系数f的测定,研究了瓦斯解吸指标K1随煤层坚固性系数f的变化特性,结果表明:瓦斯解吸指标K_1与煤层坚固性系数f之间有显著的相关性,且两者之间呈现很好的幂函数特性,与现场局部突出预测情况相符合。The relationship between gas desorption index K1 and coal sturdiness factorf was measured from the 24# coal seam of Shanjiaoshu mine based on the measuring principle of K1 and field determination method. The variation characteristics of K1 with f was researched. The results show that there is significant correlation between K1 and f. This correlation can be expressed by power function, and consistent with the local outburst pr-ediction.
