LIU Junlong
Abstract：In order to realize the balanced strip mining, stable connection and reasonable development of the open-pit mining area of Rujigou Anthracite Branch, the mine optimizes the existing mining direction of the open-pit mining area. The exploitation direction of Dafeng mining area is from longitudinal mining to horizontal mining. Yangchi mining area advanced direction changes from west to east to from north to south. The mine carries out unified, intensive optimization design on two mining areas, in order to realize the safety and efficiency utilization and sustainable development of precious anthracite resources.
