| Abstract: | Combining with the mining features and production practice in Xinli mining area of Sanshandao gold mine, the limiting grade is changed based on the current mining technical conditions and economic and technical indices. The different levels of reserves are calculated and the economic benefits are generally estimated after the grade changes. The mining practice show that not only the low-grade resources are recovered but also good social and economic benefits are obtained. |
