摘要：

For improving the efficiency of gas drainage in coal seam with low permeability, based on the micro-structural photographs, the laboratory device of gas drainage was being created, under the coequality condition of experiment, gas quantity of infusion is much more than pure drainage; The technology of Pressurization has been putting forward. The results show that the low permeability not only is the characteristic of soft coal seam, but also is the main obstacle of gas drainage. The implement of the technology can enhance Permeability of soft coal seam and efficiency of gas drainage
