Analysis of the Caving Property Influencing Factors of Top - coal in Shallow Depth and Very Thick Coal Seam
MA Yan-bin
Abstract：Based on the nature of 4# coal Seam in No. 1 Coal Mine of Pingshuo Coal Industry Company, the article analyzed influence Factors of Top - coal Caving Property in 4106 fully mechanized caving face , such as coal seam strength, mining depth, crack developing extent’s features, dirt band height, and used Method of Comprehensive Evaluation in Fuzzy Mathematics to analyze Top - coal Caving Property in 4106, the results showed that its comprehensive index value is 0. 7469, the Caving Property belongs to Type Ⅲ of middle de-gree, top coal recovery ratio generally is 50 ~ 64%.
