Project Description


 Liudong Coal Mine has a serious issue with coal seams trapped beneath buildings, water bodies, and railways (or highways), with a coal volume of 24.892 million tons affected. Using the 5,000-meter single-stage pumping system developed by FENY, the mine has achieved a paste backfill extraction capacity of 120m³/h, with a paste concentration of 84%. The system can transport the paste over a distance of more than 5,000 meters,  navigating over 120 bends.





Project Outcome


As the first domestically developed and successfully applied 5,000-meter single-stage pumping paste backfill system, it addresses the challenges of coal extraction at Liudong Coal Mine, 
improving coal recovery rates, extending the mine's service life,and preventing surface subsidence. This achievement has been awarded the Second Prize for Scientific and Technological Progress in Jiangsu Province.
