What disease often afflicts coal miners?

Black lung disease afflicts miners when they breathe excess amounts of coal dust, causing nodules to form in their lungs. This formation process causes internal scarring and stiffness, slowly reducing lung function and making breathing difficult.

What happens when mines are abandoned?

Based on the success of these projects, a new step in addressing abandoned mines has been added — reclamation. After the physical and environmental hazards are removed, the land is reclaimed. Vegetation is introduced again, and old buildings may be preserved.

What are the positive and negative effects of mining?

Specifically strip mining that can destroy landscapes, forests, and wildlife habitats that are near the sites.

What are the environmental issues associated with an abandoned mine explain with suitable examples?

The physical impacts of abandoned mine sites include: altered landscape; unused pits and shafts; land no longer usable due to loss of soil, pH, or slope of land; abandoned tailings dumps; changes in groundwater regime; contaminated soils and aquatic sediments; subsidence; and changes in vegetation.

What are three consequences of mining?

Environmental issues can include erosion, formation of sinkholes, loss of biodiversity, and contamination of soil, groundwater and surface water by chemicals from mining processes.

How dangerous is mining?

Mines are often home to many dangerous gases including carbon monoxide, hydrogen sulfide, methane, and carbon dioxide. Due to the confined spaces, these gases are not always able to escape, building up within the mine. And due to their combustible, explosive, or toxic qualities, this is a very serious issue.
