煤炭地下气化技术与残留煤炭资源利用的反思（Review of underground coal gasification technology and utilization of residual coal resources） Industry invoice development is slow, affecting social stability and unity. Chinas Fuxin, Benxi, Fushun and other coal mine cities are exhausted because of resources, bringing a series of social, economic and stability issues, the lesson is very profound. Four, the application of underground coal gasification technology mainly depends on the domestic pressure on the recovery and utilization of coal resource in Chinas energy demand, coal dominated energy consumption structure, is an important part of Chinas energy strategy. With the continuous development of economy, the exploitation and utilization of coal resources begin to come from the traditional extensive pattern The stage of modern intensive transformation, the continuous development of underground coal gasification technology, is the most vivid portrayal of this change. As early as the 1979 world coal prospect conference, the United Nations has made it clear that the implementation of underground coal mining is an important way to solve the problems existing in traditional coal mining and utilization. In the field of coal gasification technology, China has also formulated the development plan, outline and so on, and it is one of the countries that research the underground coal gasification technology earlier in the world. 1, coal invoices, underground gasification invoices type of technology, coal underground gasification is carried out under the conditions of underground gasifier, there are currently two main types of technology. First, underground underground gasifier technology. Is in the coal mine mining or abandoned underground gasification furnace, the way to establish artificial driving roadway in coal gasification, and build a closed wall in the inlet hole at the bottom of the roadway (prompted invoice pores, auxiliary holes and vents formed in the same coal gasification channel within e
