Abstract
Abstract Many factors influence coal mining, such as coal seams, structure condition, lithologic characteristics of roof and floor, and so on. The mining technology and developing methods are not the same for different geological conditions. Based on mining geological conditions and the actual situation of the coal production in Linhuan coal mine, Huaibei Coalfield, combining the fuzzy comprehensive evaluation theory and method, this paper puts forward a kind of practical and reasonable structure system-evaluation prediction index system for fully-mechanized coal mining block. This system is applied to study mining geological condition in the No.9 coal seam Linhuan coal mine, Huaibei Coalfield, China, and make comprehensive evaluation and prediction for mining geological conditions of different blocks.
