Coalmine Green Mining with Gangue Backfilling Technique

Gangue backfilling can solve the environmental pollution caused by open accumulation of gangue while significantly reducing the amount of ground settlement great value for green mining. First, using the owe design test equipment to test the mechanical properties of coal gangue; Then, according to the mechanical properties of coal gangue to improve and design the backfilling equipment; Finally, by monitoring the effect of gangue backfilling to improve backfilling technique. Through doing these works to Improve and optimize the efficiency of gangue backfilling green mining technology, solving a series of open-air environment pollution caused by open accumulation of gangue.
