摘　　要：应用内外应力场理论，根据鲍店煤矿的生产实践，结合实验室相似材料模拟研究，对分层开采，网下综放，全厚综放三种不同开采条件下的冒落岩层厚度、导水裂隙带高度、地表沉陷特征以及支承压力大小及分布特点进行了分析和探讨，并建立了相应的计算模型，为现场综放回采工作面。Based on the two stress field theory, the production practice of Baodian colliery and the material simulation test in lab, the thickness of the collapsed strata, the height of the cracked strata and the characteristics of the surface subsidence are discussed under 3 conditions: fully mechanized mining with sublevel caving, fully mechanized with subsidence caving under net and layer mining. The quantity and feather of abument pressure distribution are analysed and the respective calculation models are established. The theory foundation is offered for the strata pressure control in workface and roadway of fully mechanized mining with sublevel caving.
