tailings pumping and filling business arer hengyuan recycling technology co., ltd-尊龙登录

tailings filling is the most comprehensive utilization technology of tailings. on the one hand, more than 60% of the tailings can be filled in the underground, so as to greatly reduce the tailings discharge and land occupation, and protect the ecological environment; on the other hand, high-quality backfill can play a good supporting role in the underground goaf, avoid the collapse of the surrounding rock in the goaf, so as to effectively protect the surface of the mining area. in addition, the recovery rate of underground ore resources can be significantly improved by combining mining filling with pillar mining. compared with other mining methods, the recovery rate can be increased by more than 10-20%, and the service life of the mine can be significantly prolonged.

core equipment: the filling industrial pump can be used for the filling of goaf in ferrous, non-ferrous, gold, chemical and other mines, the filling of concrete in goaf and roadway in coal mines, the long-distance and high lift transportation of sludge in sewage treatment plants, and the dredging of rivers and lakes. the equipment is green, safe and efficient.
applicable solid content: it can pump tailings, fly ash, gangue, construction waste, fine stone and other mixed materials, with the maximum concentration up to 85%.
