Abstract
This article takes a certain coal mine as the research object,and on the basis of exploring its geological structure development characteristics,comprehensively uses fuzzy comprehensive evaluation method and grey system modeling prediction technology to predict the complexity of geological structure in the unmined area of the mine,providing reference for future mining operations.The mining area belongs to a monocline structure,with developed folds and faults.The folds are mostly short axis anticlines,and most faults have a drop of less than 1m.For the mined areas,the fuzzy comprehensive evaluation method is used to obtain the complexity of geological structures,and then three indicators,namely sandstone thickness,fold complexity coefficient,and variation coefficient of coal seam floor dip angle,are selected for grey system modeling and prediction.The results indicate that the overall complexity of geological structures in the unmined area of the mine is relatively low,making it suitable for comprehensive mechanized coal mining.关键词
