摘　　要：崩落体是无底柱分段崩落法生产流程中核心之一,对放矿作业有较大影响,目前对于崩落体形态的研究较为有限。基于离散元数值模拟对崩落体形态进行重构,并分析影响崩落体形态的因素,对地下矿山实际生产予以指导。Collapse is one of the core production processes in the pillar less segmented collapse method,which has a significant impact on ore drawing operations.Currently,research on the morphology of collapse is relatively limited.Based on discrete element numerical simulation,the shape of landslide is reconstructed,and the factors affecting the shape of landslide are analyzed to guide the actual production of underground mines.
