摘　　要：为了积极响应新形势下节能减排政策,总结归纳大佛寺煤层气抽采与综合利用,在实验研究基础上采用“瓦斯抽采+低浓度瓦斯发电+锅炉余热利用”的综合利用方式,结合实际对大佛寺煤层气的高效利用提出合理化建议。得出4#煤层裂隙宽度较大,平均10~38μm,渗透率为3.06~5.73mD,主煤层渗透率较大,渗透性较好。煤层气综合利用率较高,实现了环境、经济和社会效益。In order to actively respond to the policy of energy conservation and emission reduction under the new situation, summarize and summarize the extraction and comprehensive utilization of coal seam gas in Dafosi, adopt the comprehensive utilization mode of “gas extraction+low concentration gas power generation+boiler waste heat utilization” on the basis of experimental research, and put forward reasonable suggestions for the efficient utilization of coal seam gas in Dafosi in combination with the actual situation. It is concluded that the crack width of Coal Seam 4 # is relatively large, averaging 10~38 μ m. The permeability is 3.06~5.73 mD, and the main coal seam has high permeability and good permeability. The comprehensive utilization rate of coalbed methane is relatively high, realizing environmental, economic and social benefits.
