摘　　要：以固体资源转流态化开采的研究态势为切入点,结合煤的生物转化研究现状,探讨了原位条件下通过微生物发酵实现煤转流体开采的技术方案。从气态和液态产物综合利用角度出发,给出了煤的生物降解途径及流态化产物的生成路径;在此基础上,提出了生物流态化采煤的概念。考虑生物流态化采煤的特点,探索了生物流态化开采煤的实施方法、生产系统及工艺流程。分析了原位生物流态化采煤的关键技术及应用前景。初步搭建了煤的原位生物流态化开采的技术构想,为科学、高效和绿色采煤提供新思路。Combining the progresses and trends on fluidized mining with the application fruits of biosolubilization and biomethane of coal,this paper discussed the microbo technical conception to make in situ solid coal a flow for fluidization exploitation.From the perspective of the comprehensive utilization of gaseous and liquid products,the biodegradation pathway of coal and the formation of fluidized products were given.On this basis,the concept of biologically fluidized coal mining was proposed,which enriches the connotation of solid resources fluidized mining.From the characteristics of biologically fluidized coal mining,the implementation method,production system and process flow of biologically fluidized coal mining were explored.The key technologies and application prospects of in situ biofluidized coal mining were analyzed.The technical concept of in situ biologically fluidized mining of coal has been initially established,providing new ideas for scientific,efficient and green coal mining.
