中文摘要：

本文从影响煤层气可采性的资源量条件、渗透条件、水文地质条件、外部环境等方面入手，建立了煤层气可采性的事故树模型；根据西山矿区勘探开发资料，建立了该区煤层气可采性评价体系；应用模糊综合评价方法对该区进行了综合评价，得出该区不同矿井的评价值。结果表明：西山矿区杜儿坪矿最有利煤层气开发；屯兰矿、东曲矿、马兰矿和西铭矿仅次于杜儿坪矿；官地矿开发潜力一般；西曲矿、镇城底矿和白家庄矿的煤层气资源评价分值小，不具备开发潜力。西山矿区煤层气资源可采性评价，为降低该区煤层气勘探开发风险和成本提供了保障。

英文摘要：

The paper has built an accident tree model of workability of CBM, starting from many aspects, such as resources conditions that influence workability of CBM, permeability, hydro-geological conditions, external environment, etc. A system has been built up for evaluation of CBM workability in this area based on prospection and development data in Xishan mine area. A fuzzy method is applied for making composite evaluation of the mine area, and values for different mines in the area are obtained from this evaluation. The results show that Duerping Mine in Xishan mine area is most favorable for CBM development; Tunlan Mine, Dongqu Mine, Malan mine and Ximing mine are next to Duerping mine; the development potential of Guandi mine is fair; and the evaluated values of CBM resources for Xiqu mine, Zhengchengdi mine and Baijiazhuang mine are low, which mean no development potential. Evaluation of workability of CBM resources in Xishan mine area provides a guarantee for decreasing risks and costs in prospection and development of CBM in this mine.
