effect of backfilling on the underground environment
Contributors: Chamber of Mines Research Organization.
Language: eng
Description:   The importance of backfill in South African gold mines was explained.  As a result of this practice, stope ventilation improved, the heat load in the stopes was reduced, and the working conditions improved. Unfortunately, excess water was given off, fines escaped from the backfill, and cyanide (free and complex) was found in the water as a consequence of this practice.
