Strengthening the conservation and comprehensive utilization of mineral resources is an important way to solve the shortage of resources, an inevitable requirement to accelerate the transformation of economic development pattern, and an essential way to stimulate sustainable development of mining enterprises. Carrying out technical and economic evaluation of mineral resources conservation and comprehensive utilization is conducive to maximize the benefits of mineral resources, and improve the standard/quality of demonstration bases. By case analysis of technical and economic evaluation for a limestone mine, the article points out that the technical and economic evaluation should provide a scientific basis for mineral resources exploration and mining, and guide the development of mineral resources conservation and comprehensive utilization projects.%加强矿产资源节约与综合利用是解决我国资源短缺的重要途径,是加快经济发展方式转变的必然要求,是促进矿山企业可持续发展的必由之路.开展矿产资源节约与综合利用技术经济评价有利于实现资源开发利用效益最大化,有利于提高示范基地建设水平.通过对某石灰石矿技术改造项目技术经济评价案例的分析,指出技术经济评价应为我国矿产资源综合勘查开采提供科学依据,为矿产资源节约与综合利用项目开展时序提供依据.
