基于结构元方法的巷道煤体破碎程度综合评判

Comprehensive evaluation of roadwaybody broken level based on structure element method

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,根据煤层地质构造、煤的硬度、压力参数、瓦斯在煤体中的赋存情况等因素,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采煤工艺的选择提供依据。

In view of the fact that the roadway excavation or mining production process,the broken coal directly affect the level of roadway support method and mining techniques,based on the coal seam geological structure,coal hardness,stress parameters,mining methods,and roadway parameters and other factors,with the structuring element method,the structuring element expressions of fuzzy is given,on this basis,the broken extent of roadway is comprehensively evaluated.And thus a more objective evaluation of the breaking a class is evaluated,providing the basis for the selection of the scheme of roadway support and mining techniques.
