摘　　要：我国煤层瓦斯赋存普遍有"高储低渗"的特点,为提高煤层渗透率,强化煤层瓦斯抽采,提出了煤层注热理论。为了进一步研究注热工艺和开发注热装备,对注热相关理论和工艺研究现状进行了梳理,并提出了目前存在的问题和未来研究思路。The coal-seam gas in our coal mines generally has the feature of “high reserve and low permeability”. In this paper, the heat injection theory was proposed in order to improve the gas permeability of coal seams and reinforced the gas drainage from seams. For further studying the heat injection technology and developing the heat injection equipment, the theory and technological research status related to the heat injection were combed, and the existing problems and future research thinking were put forward.
