摘　　要：对于顶板结构的合理分析,是保障工作面安全生产的基础。本文根据东曲矿8号煤层实际地质资料为工程背景,利用理论计算的方法,对工作面顶板进行分类;综合多种方法的计算结果,确定工作面的"两带"高度;依据前面对煤层顶板的分析结果,对工作面的支架工作阻力进行合理推测。研究结论为煤层正常开采奠定了基础,为工作面支架选型提供了理论依据。The reasonable analysis of roof structure is the basis of safe production of working face.Based on the actual geological data of 8#coal seam in Dongqu coal mine,use theoretical calculation method to classify the top plate of the working face.The calculation results of multiple methods are used to determine the height of caving zone and fissure zone.Based on the analysis results of coal seam roof,it is reasonable to speculate on the resistance of the working surface.The research conclusion lays the foundation for the normal mining of coal seam,and provides the theoretical basis for the selection of working face bracket.
