【摘要】 针对煤巷掘进或采煤生产过程中,煤体的破碎程度直接影响着巷道的支护方式和采煤工艺.利用结构元方法给出模糊综合评判的结构元表达形式,在此基础上,根据煤层地质构造、煤的硬度、压力参数、采煤方法等因素.对巷道煤体破碎程度进行综合评判.进而较为客观地评价出其破碎类别,从而为巷道支护方案和生产措施的选择提供依据.更多还原

【Abstract】 On the roadway excavation or mining production process,The broken coal directly affect the level of roadway support method.Based on the coal seam geological structure,coal hardness,stress parameters,mining methods,and roadway parameters and other factors,Use of experts to-point method to determine the weights of various factors,Using the structuring element method gives fuzzy comprehensive evaluation of the structuring element expressions, On this basis,the broken body of the extent of roadway comprehensive evaluation.And thus a more objective evaluation of a class of its broken,so as to roadway provide the basis for selection of the program.更多还原
