Brief Description
Description : | 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. |
