Since the reform and opening up, with the development of continuous mining technology and scale expansion of open pits, the design philosophy of current mining procedure and mining technology has gradually lagged behind. For the development of large-scale opencast coal clusters in china, the paper analyzed the backward design philosophy of traditional industrial square-centered mining procedure under the original shovel-truck technology, and put forward a new design idea of banded subarea mining. On this basis, for large-scale open pits, the paper further proposed the stripping technology of shovel – self advancing crusher – double-face belt conveyor in combination with the raw coal transport technology of shovel – truck – simple mobile crushing station – end slope belt conveyor. These new technologies have already been applied to Pingshuo East surface mines, providing references for future development of China’s large-scale opencast coal mines.
