Project Summary
Supply of filling equipment for Henan Pingmei No.11 Mine Project
Case of coal gangue cemented filling
Introduction/Effectiveness
Pingdingmei No.11 Mine adopts green coal gangue cemented filling technology with a filling capacity of 400m.3/h, the project has a long horizontal conveying distance. The filling industrial pump provided by Hunan Yutai has a single horizontal conveying of 4000 meters. Using four pumps and two-stage relay mode, the total conveying length is 8000 meters, which solves the problem of large amount of long-distance coal mine paste filling, prolongs the service life of the mine, improves the coal mine extraction rate, avoids ground subsidence, and realizes the green mining of coal mine.
