Based on the green mining concept of coal mine, connotation and technology system of green mining of manganese resources were expound. According to the problems on the mining and utilization procedure of manganese resources, the green mining of manganese was suggested. It included the water preserving mining technology, reducing subsidence mining technology, non-waste mining technology, as well as comprehensive utilization technology of other associated resources. The main key issues were in-depth analyzed in this paper, and the recommendations for the further research and development were proposed.
Based on the actual data of Xiushan County and Chinese manganese demand, GM (1, 1) model was established to predict the manganese demand. The prediction accuracies of Xiushan’s manganese demand, Chinese manganese production and exports were respectively 95.5%, 94.5% and 96.3%. Residual error test showed that the model was reliable and could be used to predict the manganese demands in the future five years. And the demands would be grown exponentially with time. The predictive results indicated that the supply safeguard was worrying.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
