occupational health hazard point of view and for devising appropriate dust control strategies in underground metal-liferous mines. Use of electric LHDs though eliminates diesel exhaust fumes and DPM hazard in underground working environment, the mineral dusts generated owing to their use could pose health hazard. Keeping this in

Map of sampling sites of studies on toxic environmental hazards in artisanal and small-scale gold mining, related human exposure, and health impacts in Africa.

African countries were identied. Toxicological environmental hazards were reported in 102 peer-reviewed papers, notably As, Cd, CN, Cr, Hg, Pb, respirable SiO 2-laden dust, and radionuclides. Exposure to PTEs in human biomonitoring matrices and associated health impacts were documented in 71 papers. Hg was the most reported hazard.

issues in the management of those hazards are discussed. Hazards from mining processes Mining involves rock drilling, related milling opera-tions and dredging.6 These processes generate copious amounts of dust, which is mainly made up 1Toxicology Section, National Institute for Occupational Health, Johannesburg, South Africa

Almost all the unit operations of mining generate significant amounts of airborne dust, which poses a serious health hazard to miners. Dust may be defined as small solid particles below 75 μm in diameter, which may remain suspended for some time [], whilst particulate matter (PM) is a mixture of solid particles and liquid droplets of varying composition and masses.

When inhaled in large quantities, the body's defensive mechanisms can be overwhelmed. 2. In mining, it is common to have a mixture of dusts due to mining the roof or floor or both [the country rock] with the coal seam or the ore body. Other sources of dust include rock dust, wood supplies, and diesel engines, if used.

An ore processing plant presents numerous safety hazards throughout its various stages of operation, including haulage, primary stockpiles, crushing, screening, conveyors, surge piles, washing plants, electricity, plant maintenance, and general mining hazards. These risks encompass vehicle accidents, falling materials, machinery-related injuries, electrical dangers, …
