Project Overview
Conventional hydraulic filling requires additional work elements as well as man power for its application in underground coal mines. For instance, it requires sophisticated underground porous retaining barricade structures, re-handling of surplus water and there is a risk associated in form of failure and flow of backfilled material. However, paste backfill technology is an improved and effective option as compared to conventional mine stowing.
