Process Description

Mining activity consists of cyclical activity. It consists of removal of overburden with the help of dozers, loaders and tippers. The exposed gypsum is blasted after drilling. The blasted material is sorted by labourers and stacked as boulders or dust. The material is loaded into the trucks either by front-end wheel loaders or manually from the site depending on whether it is dust or boulder. The loaded truck is then covered with tarpaulin to avoid loss of material and to control of dust during transport. Each truck carries about 9 MT of gypsum from Pema Gatshel to Samdrup Jongkhar. The dust is loaded by wheel loaders and the boulders manually into trucks and transported to Samdrup Jongkhar dump-yard for selling to the end users.
