摘　　要：煤层气是矿井灾害频繁发生的直接原因,但是煤层气作为一种清洁能源备受关注。我国是世界煤层气储量大国,开发和利用煤层气将解决我国的能源紧缺问题。同时由于我国煤层气自身的特点,开采煤层气具有一定的困难。论文介绍了一种煤层气开采技术,利用该项技术可以大大提高煤层气的渗透性,增加煤层气的产量。The coal gas is the directly cause frequently taking place in calamity of the mine, but the coal gas was concerned as a kind of clean energy. It has a big reserves in our country, develop and utilize it will solve the problem that energy shortage in our country, At the same time because of the characteristic of coal gas of our country, it is difficulty to mine. This article has introduced a kind of technology about coal gas is exploited, The penetrance of the coal gas will be improved greatly and the output of the coal gas after utilized this technology,
