摘要：According to the energy structure characteristics in China, this paper analyzed the current situation of liquefaction and gasification exploitation of coal as an emerging mining method. Simultaneously, setting the UCG(UCG) as an example, this paper analyzed the factors impacting the new-type mining method of coal resources and the mining damages, obtaining that the main damages of UCG include surface subsidence, groundwater pollution and other pollution. This paper, which proposed to evaluate the environmental benefits of the new-type mining method, established a evaluation system of environmental benefits of UCG and adopted fuzzy comprehensive evaluation, obtaining four-class comprehensive evaluation indexes of the new-type mining method.
