| 摘 要： | 通过研究分析目前国内外煤层气开发模式,结合重庆地区实际地质情况,提出了适合重庆地区的综合开发模式。即:采煤前地面压裂抽采,预抽原始煤层的煤层气;采煤时井下预抽,利用采掘工作的超前压力,开采卸压,进行井下煤层气抽采;采空区及废弃矿井煤层气抽采,通过地面钻井、埋管及巷道抽采煤层气;以及矿井通风煤层气的回收利用。形成了煤层气综合性规模开采的一种最为经济、有效的模式,同时也指出了这一模式需要解决的主要问题与关键技术。

| Abstract: | Combined with actual geological conditions of Chongqing Area,a comprehensive development mode of coal-bed-gas was put forward by analyzing current development modes in domestic and overseas.That is: surface draining gas in original coal-seam before mining,underground drainage in mining pressure-relief area and draining gas in gob and refused mines by surface drilling,utilizing buried pipe and roadway and collecting gas in ventilation.It was a most economical and effective mode of coal-bed-gas comprehensive ... |
