Abstract: Mine geo-environment risk decision making is a consultation process to meet multiple objects from multi-stakeholder. In order to control mine risk in the mine life cycles, the decision making was employed to approach three objects which were meeting acceptable risk, getting the most benefit from control engineering and making reasonable plan for mine closure. Then, the hierarchical analysis was applied to multiple criteria decision making in risk management of mine geo-environment. Lastly, the consultation process was used to determine the engineering proposal that control the geo-environment risk of a limestone mine in Fengshan, Guangxi. The process considered some information from multi-stakeholder including design organization, government and local people. It indicates that the optimal engineering proposal has four parts, i.e. P1 with cutting slope, clearing up unstable rock and anchoring; P2 with drainage, rockfall platform and monitoring; P3 with smoothing slope surface, carving and vegetation; P4 with risk education. It is not only a guidance to rebuilt environment of the limestone mine, but also has positive affect to develop mine closure.
