Abstract：In order to treat the uncertainty of abstract concepts and qualitative language in the process of geology adaptability evaluation of underground coal gasification with narrow strip,a new comprehensive evaluation method based on cloud model was presented.Firstly,the geologic factors which had effect on UCG were selected as evaluation factors to construct evaluation index system and the weights were determined respectively.Secondly,the evaluation cloud models of the secondary factors were established through the experts estimation,then the secondary evaluation clouds and the primary evaluation clouds were aggregated by using the algorithms of the floating cloud and the comprehensive cloud respectively to obtain the comprehensive evaluation cloud.Finally,the comprehensive evaluation cloud was compared with the evaluation criteria concept cloud in cloud chart to get the evaluation results.The results show that this method whose logic is easy to understand,calculation process is simple,evaluation results are visual and reliable,is suitable for using in geology adaptability evaluation of UCG with narrow strip.
