Assessment of mine ventilation systems and air pollution
Blasting activities produce large amounts of fumes and toxic gases at Merelani. Ammonium Nitrate-Fuel Oil (ANFO) is commonly being used for blasting. CO NO and NO 2 are the main fumes of concern produced after blasting. Due to low air velocity from compressors it usually takes about 4 h to clear out fumes after blasting.
