Fuzzy optimization for CBM favorable targets based on combined weights
Abstract：To optimizing coalbed methane（CBM） favorable targets in western Guizhou Province and eastern Yunnan Province, six typical areas were focused on to estimate which should be explored preferentially. Firstly, nine parameters in three categories, e. g. the coal reservoir, the resource conditions and the exploitation infrastructures were concentrat- ed to form an evaluation matrix. Subsequently, the matrix was weighted by a vector that combined the grey correlation analysis and the analytic hierarchy process（AHP） and was calculated in a fuzzy multi-objective and multi-level opti- mization model. Finally, the results of the calculation were drawn on a thematic map. It indicate that the optimal target is the Zhina Coalmine, and the Panxian Coalmine is suboptimal as well as the Laochang, Liuzhi and Shuicheng Coalmines. By contrast, the Enhong Coalmine is unfavorable.
