摘　　要：为了考察方山新井二1煤层突出危险性预测指标临界值,运用瓦斯吸附解吸实验,分析煤层瓦斯吸附解吸特征,对实验数据进行统计分析并回归得出了瓦斯含量w和瓦斯压力p、瓦斯解吸指标V1、瓦斯解吸指标V1和瓦斯压力p之间的关系,最终基于瓦斯膨胀能确定了二1煤层突出危险性预测指标瓦斯含量w的临界值,为研究制定抽采效果评价指标体系提供科学依据。In order to predict the outburst risk prediction critical value index on 2, coal seam of Fangshan New Well, it made desorption characteristics of gas acoal seam dsorption by using gas adsorption and desorption experiments,it made statistical analysis of experimen- tal data and regression that relationship between the gas content W and gas pressure P, gas desorption index V,, the relationship between gas desorption index V, and the gas pressure P, it determined that 2, Coal Seam outburst risk prediction index gas content W critical val- ue based on the gas expansion energy, it provides scientific basis for studying and formulating the drainage effect evaluation index sys- tem.
