利用永久设施建井是矿井建设中常用的一种施工措施。针对目前我国利用永久设施建井工作中存在的问题,提出了合理利用永久工程的原则,根据利用永久工程建井的经验,建立了利用永久工程建井的经济评判模型,运用现代工程经济评价原理对拟利用的永久工程方案进行了经济合理性评判,从而确保在矿井建设中实现减少投资、缩短工期等目标。 The use of permanent facilities to build wells is a commonly used construction method in mine construction. According to the existing problems in the construction of permanent facilities in our country, this paper puts forward the principle of rational use of permanent works. According to the experience of using permanent engineering to build wells, the economic evaluation model of using permanent engineering to build wells is established. By using the principle of modern engineering economy evaluation, The proposed permanent construction project has been economically justified, so as to ensure the goal of reducing investment and shortening the construction period in mine construction.
