摘　　要：根据顶煤冒放性的影响因素,基于模糊数学理论以地质影响因素为指标对大阳煤矿3号煤进行顶煤冒放性研究,结果表明3号煤直接顶为2类,基本顶为3级,顶煤冒放性好(Ⅱ类),对生产实践具有指导作用。According to cavability factors,geological factors,as the indicators,were used to study the top coal caving on the No.3 coal seam in Dayang Mine based on fuzzy theory.The results show that the immediate roof of No.3 seam is type II,the main roof is grade 3,and the top coal caving is good（type II）,which could provide the guidance for the production.
