Abstract: According to at mining enterpriseDs production and management characteristics and information demands, the conception of smart mine based on auto mated mine, digital mine and intelligent mine was demonstrated. Based on the concept of smart earth, a smart mine was instrumented, interconnected and intelligent, W hich represents three core features. Then, smart mine system architecture including perception layer, interconnection layer and intelligent layer were built by theoretical analysis of mining system engineering and mine engineering value chain. Further, key techniques and its implementation path were discussed, so as to build theoretical framework and methodology for smart mine, and provide guidance for smart mine engineering practice.
