Recycling Scheme of Non-metallurgical Limestone Above 400 m Level of Dabaopo Mine in Chongqing City

Abstract

Abstract: The non-metallurgical limestone resources is exposed in large scale during the mining process of Dabaopo Mine in Chongqing City,in order to improve the resource utilization rate,the recycling scheme of the non-metallurgical limestone is proposed.The economic and rationality stripping ratio of the non-metallurgical limestone above 400 m level of the mine is determined,the incongruous contradiction of the optimization and equalization of production stripping ratio of the mine is solved,the new ideal of mine circular economy development is proposed,which can provide reference for the other mines.

Key words: Open-pit mining, Non-metallurgical limestone, Economic and rationality stripping ratio, Recycling
