Coal Gangue Gypsum Paste Backfill Equipment Case

Case Type

Using FENY's paste backfill system, several key technologies, including simultaneous mining and backfilling, have been achieved.

Project Description

At Dali Mine, the use of paste backfill has extended the mine's service life by over 7 years. Yangdong Mine has increased its high-quality primary coking coal reserves by 13 million tons through paste backfilling, while Xinsan Mine has added 17 million tons of high-quality primary coking coal. The full mining and full backfilling approach will completely eliminate the existing gangue hills, prevent surface subsidence, and protect arable land,ensuring that gangue hills no longer occupy farmland. This also reduces costs. The project was awarded the First Prize for Scientific and Technological Progress by the China National Coal
