Abstract

To improve coal recovery rate of open pit coal mines, according to the conditions of coal seams at flat dipping open pit coal mines in China, a new mining system for recovering remaining coal around end-slopes was proposed. This system can extract the end-slopes coal remnants which are normally abandoned in traditional mining systems by using existing open pit mining and transportation systems. In this system, lower initial investment, mining and transportation costs are available, so the economic benefits are good. Moreover, the main mining parameters were discussed, and all of these results can be referred by the other open pit mines with similar geological conditions.
