For almost 100 years, Zambia has been highly dependent on copper and the mining industry, and the country is living proof that progress leaves its mark on both the environment and people''s health. Land degradation. Increased deforestation. Water and air pollution from particles of sulphuric acid, which severely affect those residing near mines.
Environmental hazards are present during every step of the openpit mining process. Hardrock mining exposes rock that has lain unexposed for geological eras. When crushed, these rocks expose radioactive elements, asbestoslike minerals, and metallic dust.
The principal airborne hazards in the mining industry include several types of particulates, naturally occurring gases, engine exhaust and some chemical vapours; the principal physical hazards are noise, segmental vibration, heat, changes in barometric pressure and ionizing radiation. These occur in varying combinations depending on the mine or quarry, its depth, the composition of the ore and ...
