中文摘要：
为了合理选择露天矿采区转向过渡方式,从生产稳定、技术管理、经济效益3方面选取12个指标建立了采区转向优选评价指标体系,利用模糊综合评价方法,建立了露天矿采区转向方式优选模型。以霍林河北露天矿为例,利用优选模型计算得出留沟缓帮方案为三采区最佳转向过渡方案。
英文摘要：
In order to reasonably choose the open-pit mining transition mode, the optimization evaluation index system of open-pit mining transition mode is established by selecting 12 in- dicators from three aspects of stable production , technical man- agement and economic benefit. An open-pit mining transition mode optimization model was built by using the fuzzy comprehen- sive evaluation method. Taking North Opencast Mine in Huolin- he as an example, the calculation results show that the turning box retained with the gently inclined slope scheme is the optimal mining transition mode by using the optimization model.
