Design and evaluation of coupled developing projects considering regional development and sustainable environment

当地下结构达到其原有的使用寿命后，从环境系统的角度出发，有必要对其进行持续的维护和控制，以减少对周边环境的影响。探讨了地下空间更新作为地下空间维护和控制措施的可行性。以某活跃煤矿为例，提出了地下抽水蓄能发电系统及煤矿废水利用方案。然而，在推进这一项目的同时，准确预测该地区的经济连锁效应是非常重要的。本研究不仅讨论了UPSPG项目和水资源开发项目的详细设计，而且采用产业关联分析的方法，比较了这些项目的建设、管理和煤矿活动所产生的经济连锁效应。

When an underground structure finished its original service life, it is neccessary to conduct its continual maintenance and control to decrease the impact on neighborhood from the environmental system viewpoints. The authors have discussed the feasiblity on underground space renewal as a measure of maintenances and controls of underground spaces. As an example, a plan of the underground pumped-storage power generation system (UPSPG) and the utilization of waste water from the coal mine which cohabits with an active coal mine was proposed. However, it is very important to predict the accurate economical ripple effect to the region accompanied by promoting such a project.This research discusses not only the detailed design of the UPSPG project and the water resource development project, but the comparison of the economical ripple effect in accordance with construction, management of these projects and activity of the coal mine by the industrial linkage analytical method.
