Sources and Impacts of Air Pollution in Mining

Air pollution mining is unavoidable due to the essential activities required to extract raw materials from the earth. Understanding the sources of air pollution in mining and its impacts is key to designing robust control systems.

Major Sources of Air Pollution from Mining

  • Drilling and blasting: Release large quantities of particulate matter (PM), including silica and heavy metal-containing dust.
  • Excavation and crushing: Generate airborne particles which can travel far, impacting local ecosystems and communities.
  • Transportation of ore and waste: Especially on unpaved roads, stirs up dust and at times leads to secondary dust liberation.
  • Diesel-powered machinery: Emits gaseous pollutants like NOx (nitrogen oxides), SO2 (sulfur dioxide), hydrocarbons, and carbon monoxide.
  • Tailings dams and waste piles: Dried out, they become sources for fine particulate matter to become airborne, mostly in dry and windy conditions.

Impacts of Mining Air Pollution

  • Health risks: Inhalation of PM10, PM2.5, and toxic metals leads to respiratory and cardiovascular diseases among miners and populations in nearby communities.
  • Environmental degradation: Deposited dust adversely disrupts soil, vegetation, and water sources, while gaseous pollutants can acidify ecosystems.
  • Regional air quality degradation: Mining regions may experience persistent haze, poor visibility, and ecosystem imbalance due to emissions.
  • Climate change: Mining activities contribute to GHG emissions, especially with energy-intensive infrastructure.
  • Regulatory compliance: Failure to control mining emissions often leads to fines, project shutdowns, or loss of license.
