摘要
根据公乌素煤矿1604综放工作面16#煤层实际地质条件,采用模糊数学分类方法,以煤体强度、裂隙分布、夹矸影响、开采深度、煤层厚度、顶板岩性等6个因素,为指标对顶煤冒放性进行分析。研究结果表明,16#煤层顶煤冒放性好(Ⅱ类),对该煤矿的生产实践具有重要的指导意义。
According to 16# coal layer actual geological conditions of 1604 fully mechanized caving face in Gong- wusu coal mine, the paper analyzed top -coal caving characteristics according to the following six factors, such as coal intensity, roof fissuring and cracks, coal bed dirt layers, mining depth, coal seam thickness, roof rock characters and so on by using the classification method of fuzzy mathematic. Results indicate that the top - coal caving characteristics in 16^# coal is extremely good（ II ） , and it has an important guiding significance for producing practice of Gongwusu coal mine.
