Apr 25, 2017· Mining adversely affects the environment by inducing loss of biodiversity, soil erosion, and contamination of surface water, groundwater, and soil. Mining can also trigger the formation of sinkholes. The leakage of chemicals from mining sites can also have detrimental effects on the health of the population living at or around the mining site.
The aim of the present study was to investigate if underground miners exposed to dust and diesel exhaust in an iron ore mine would show signs of airway inflammation as reflected in induced sputum. In total, 22 miners were studied, once after a holiday of at least 2 weeks and the second time after 3 months of regular work. Control subjects were 21 "whitecollar" workers.
Fine invisible coal dust particles less than microns long lodge in the lungs and are not naturally expelled, so longterm exposure increases the risk of health problems. More exposure increases risk. The health risks increase with the level and frequency of exposure.
particulate matter (PM), can damage our health. • PM10 particles measure between and 10 micrometers (from 25 to 100 times thinner than a human hair). These coarse particles cause less severe health effects. They are often visible, and are caused by smoke, dirt and dust from factories, farming, roads and mining.

Health problems due to mining: 1) The toxicity of metal can cause problems due to mercury, fluorine and also arsenic. These metals enter the food chain and affect all the animals in suit. 2) Mining also cause lung defects like Pneumoconiosis which is due to the inhalation of coal and other dust particles in the process of mining.
Mining, maintenance or processing activities can result in the release of dust particles into the air. Exposure to dust in mining and quarrying continues to be a major risk to the health of workers. Breathing in dust, such as coal dust, silica dust and other finely powdered materials, can damage the lungs and airways.
Tiny particles of dust can be released into the air through the cutting, grinding, or drilling of rocks or products containing silica. The inhalation of this silica dust can cause silicosis, a debilitating and sometimes fatal lung disease, as well as other health problems. Usually people are exposed to silica dust at their workplace.
When companies break up materials during mining, the dust can release a variety of heavy metals commonly associated with health problems. As dust, these minerals (such as the asbestoslike mineral riebeckite) can be absorbed into lung tissue, causing problems like pneumoconiosis and silicosis, commonly known as "Black Lung" (Paul Campbell, 2011).
