摘    要:以贵州玉舍煤矿1号煤层煤样为研究对象,利用自主研发的三轴渗透仪,进行了温度和平均有效应力条件下的三轴渗流实验,分析了两者对渗透率的综合作用,得出随温度的升高,渗透率呈减小趋势,但下降梯度不大;随着平均有效应力的增大,渗透率急剧下降,下降的梯度较大。

关 键 词:平均有效应力  温度  渗透率  型煤

Abstract:The coal samples of No.1 coal seam which were taken from Yushe Coal Mine in Guizhou Province were used to do experimental subjects,and took coal samples to do tri-axial permeability experiments on conditions of stresses and temperatures,with self-made tri-axial instrument.According to the experiment results,the comprehensive effort of stress and temperature was analysed,the rate of permeability would decrease when temperature increasing,but the gradient of descent was not obvious.With the average effective stress increasing,the rate of permeability slumped,the gradient of descent was obvious.
Keywords:average effective stress  temperature  permeability  coal samples
