Abstract:With gradual consumption of surface ground bauxite resources, the exploitation of underground bauxite resources is getting more important. During the exploitation, it is a crucial step to choose an appropriate mining method. Maochang Aluminum Mine, an underground bauxite in China, has been found with a great storage of bauxite resources. Hence, there needs a proper mining method to exploitate the available resources in Maochang Aluminum Mine. This paper firstly used both AHP and weighted sum method to choose a initial mining method with synthetically considering economic indicators like the cost of mining and technical indicators like KT stripping ratio, as well as safe indicators like atmospheric conditions. In using AHP to calculate the weight of each criterion, and sub criteria based on the calculated by the principle of weighted sum of the Ci value of primary scheme.Furthermore, the room and pillar mining method is chosen to be the most proper mining method for Maochang Aluminum Mine with the value of Ci equalling to 0.4788. With the promotion of this chosen method, the exploitation of bauxite resources in Maochang Aluminum Mine has been working with high efficient. The cost of bauxite resource exploitation is also economic friendly, which satisfies the purpose of mining activity.This indicates that the evaluation method can also be used in other similar projects.
