Abstract: With the continuous development of intelligent mining technology,the mining model needs to be continuously innovated. At present,there are still many urgent problems that should be tackled in the intelligent construction of open-pit mine in China. The traditional mining design and technology can no longer adapt to the development of unmanned,new energy and other intelligent equipment,and new challenges are proposed to the original production mode and equipment under the background of " dual carbon" . By reviewing the current status of intelligent construction of open-pit mine,this paper focuses on the transformation and upgrading of low carbon intelligent mining under the background of " dual carbon" ,and explores a new mode of low carbon,continuous,efficient and safe intelligent construction named as the CDEC mining mode. The mode includes four aspects:clean energy development and carbon storage and utilization ( Carbon),new concept of open-pit mining design (Design),customized scheme of new energy intelligent equipment (Equipment) and continuous production process of open-pit mine (Continuous). Then,the technical path of this mode is explored from three aspects:establishing a renewable energy system with multiple energy sources complementing each other,exploring a low-carbon continuous production process in open-pit mine,and developing a carbon storage and ecological carbon sink technology system. In the end,the green energy supply and utilization style of " renewable energy utilization+ new energy equipment + carbon storage and utilization" will be realized,and the unmanned continuous production process of " mobile surge loader (optional) + unmanned driving + crushing system + belt transport or lifting device" will be formed,thus providing guidance for the intelligent construction of open-pit mine under the background of " dual carbon" .
