Abstract: In view of the large output of gangue in Shendong high-strength mining, and the limitations of existing gangue utilization and disposal methods, resulting in insufficient digestion capacity of gangue, a large-scale utilization mode of coal gangue in Shendong high-strength mining was proposed. The production and actual production conditions of coal gangue in Shendong mines, the actual situation of Shendong mining area and the distribution of surrounding industries, and the utilization ways of coal gangue in each mine were analyzed. The processing capacity, technical advantages and disadvantages of coal gangue utilization methods such as coal gangue power generation, coal gangue paving, coal gangue brick, sand and ceramsite, and coal gangue filling were summarized. The large-scale utilization mode of coal gangue in Shendong mining area was constructed. That is to give priority to the needs of local and surrounding industries to realize the resource utilization of part of coal gangue on the ground. Combined with the recovery coal pillar and disaster management of the mine, the gangue filling mining consumes most of the remaining gangue, and the application of filling mining shall not affect the mine yield. At the same time, the filling method is appropriately optimized, and the “ one mine, one policy ” is accurately implemented. The classification and precision filling mode of Shendong underground is formed, such as strip cemented paste filling, fully mechanized paste filling, grouting filling, solid filling, “ mining-concentration-filling ” integration filling and multi-mode comprehensive filling. This ' ground resource utilization + underground precise filling ' gangue large-scale utilization mode can maximize economic benefits and gangue disposal and disaster management benefits. The study can provide guidance for large-scale utilization of coal gangue in high strength mining area.
