Dec 17, 2016 Types of Water Pollution from Mining. There are four main types of mining impacts on water quality. 1. Acid Mine Drainage Acid Rock Drainage ARD is a natural process whereby sulphuric acid is produced when sulphides in rocks are exposed to air and water. Acid Mine Drainage AMD is essentially the same process, greatly magnified.

For water to cause problems in underground mine sites there must be a water source nearby and there must be a mode of entry for the water to reach the mine. Inflow rates of water depend on the type of water sources present, and the route traversed to reach the mine. Sources of water near mine sites depend on the regional climate and hydrogeology.

of unwanted ground water. These water inflows into the underground mine sometimes present considerable problems to mine operators. Depending on amounts and location of inflows, the water needs to be removed from active mining areas. Environmental concerns, law, and regulation require coal mines only to discharge water of an acceptable water quality.
Mine closure and down-dip mining are also considered in reducing acid mine drainage formation. The design of water-handling systems in a mine is covered in detail. The system must be integrated throughout a mine. Methods of determining pump requirements and size, pipe sizing, and various types of acid mine drainage treatment are discussed.
