煤层气是一种洁净的新能源，我国煤层气储量十分丰富。开发煤层气的方法有地面钻井开采和井巷开采两种，其中井巷开采方法适用于我国许多矿区。本文分析了我国煤层气藏的地质条件，提出了综合采煤采气要求布置井下巷道，改进传统瓦斯抽放工艺开采煤层气的井巷全量开采法，并对本方法进行了理论上和实践上的论证。
CBM is a clean new energy, China’s CBM reserves are very rich. There are two kinds of methods for developing CBM: ground drilling and roadway mining, among which, the method of mine shaft mining is suitable for many mining areas in China. This paper analyzes the geological conditions of coalbed methane reservoirs in China, and puts forward a method of fully exploiting the fully mechanized mining of coal mine gas, which is required to arrange underground tunnels and improve the traditional coal gas drainage technology. In addition, this method is theoretically and practically applied Argument
