摘要
根据采空区的赋存状态及作业设备,采用长宽比梁板法计算了采空区顶板安全厚度,引用采空区顶板稳定性数值模拟分析,从而确定了安家岭露天矿采空区顶板合理的安全厚度,保障安全过度采空影响区域。
According to the occurrence state and operation equipments in goaf, the author adopts the length-width ratio beam slab method to calculate roof safe thickness in goaf, and quotes the numerical simulation analysis of goaf roof stability to determine the reasonable safe thickness of goaf roof in Anjialing Open-pit Mine, which ensure to safely pass through goaf influenced areas.
