淮北矿区煤层气抽采利用技术探讨

淮北煤田位于能源缺乏的华东腹地,富集大量的煤层气资源。本文介绍了淮北矿区煤层气赋存情况、抽采方式和利用现状,针对淮北矿区的煤层地质条件,指出目前煤矿瓦斯抽采和利用的难点,提出在煤矿开采所造成的地层扰动下进行瓦斯抽采,进而叙述了“一井三用”的煤气共采的新途径。

Discussion on Technology for Drainage and Utilization of CBM in Huibei Mining Area

Huaibei Coalfield, with rich CBM resources, is situated in the backland of East China where energy resources are in shortage. The paper describes the occurrence of CBM in Huaibei Mining Area, the drainage method, and current status of utilization. Based on the geological conditions of coal seams in Huaibei Mining Area, it points out the difficult points in drainage and utilization of coalbed methane, as well as the method for draining the gas under the strata disturbance induced by coal mining. It describes the new approach for co-mining of coal and CBM by "using one well for three purposes
