摘　　要：以贵州矿区玉舍煤矿1#煤层40~60目的型煤试件为研究对象,借助自主研发的三轴渗流设备开展了不同含水率和温度条件下的三轴渗流试验,系统研究了水-热耦合作用对含瓦斯煤渗透率的影响规律,为瓦斯灾害防治和煤层气开发利用提供理论依据。Triaxial seepage tests under different water content and temperature is carried out with independent Triaxial seepage experiments, taking the 40～60 mesh briquette specimens of No. 1 seam of Yushe coal mine in Guizhou as study objects. The influence of water and thermal coupling on the permeability of coal containing is studied systematically, which provides a theoretical basis for the prevention and control of gas disaster and the development and utilization of coal bed gas.
