Case Type

Coal Gangue Gypsum Paste Backfill System EPC Case

Project Description

The project involves a thorough study of the characteristics of mined-out areas in the Shangwan and Bulianta coal mines. It employs a series of processes including crushing, ball milling,slurry preparation, paste preparation, intelligent sorting of gangue,and intelligent control. The gangue produced after coal mining and washing is converted into a paste and injected into the mined-out areas. Additionally, the intelligent gangue sorting system separates some of the gangue for use as underground road bedding.

Project Outcome

Achieve the resource utilization of gangue, ensuring mine safety, efficiency,environmental friendliness, and sustainable development.
