Mining and Water Quality USGS

Acid mine drainage (AMD) consists of metal-laden solutions produced by the oxidative dissolution of iron sulfide minerals exposed to air, moisture, and acidophilic microbes during the mining of coal and metal deposits. The pH of AMD is usually in the range of 2–6, but mine-impacted waters at circumneutral pH (5–8) are also common.

Coal mining Wikipedia

Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is called a 'pit

ConclusionsQuality of ROM coal depends not only in-situ quality of coal but also the mining method applied, i.e., dilution of top coal during caving is of major importance. Quality of ROM coal can be estimated by using geostatistical methods prior to actual mining operations. This will certainly facilitate realistic production planning.
