Comprehensive assessment on suitability of full mechanized coal mining technology in the thinner middle thick coal seam

摘要

According to the characteristics of fully mechanized mining technique in thinner middle thick coal seam of Yuanzhuang coal mine, using the principle of fuzzy mathematics to build up the hierarchy analysis model of thinner middle thick coal seam mining technology of geological condition and comprehensive evaluation system.The influence factors and evaluation index of comprehensive evaluation model are obtained, the results can provide a theoretical basis and quantitative standard adaptability for thinner middle thick coal seam mining technology.
