Aug 22, 2018· Coal Mine Fires (Image Courtesy: https://commons.wikimedia.org) Acid mine drainage. Acid mine drainage is created when water mixes with coal and other rocks unearthed during mining, taking on toxic levels of minerals and heavy metals. This toxic water leaks out of abandoned mines to contaminate groundwater, streams, soil, plants, animals and
(PDF) Acid Mine Drainage Control and Treatment
Acid mine drainage (AMD) forms when sulfide m inerals are exposed to oxidizing conditions in coal and metal mining, highway construction, and other large-scale excavations. There are many types of
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 a 'pit', and
An Explanation of Acid Mine Drainage ThoughtCo
Nov 13, 2019· It mostly occurs where mining is done to extract coal or metals from sulfur-bearing rocks. Silver, gold, copper, zinc, and lead are commonly found in association with metal sulfates, so their extraction can cause acid mine drainage. Rainwater or streams become acidified after they run through the mine’s tailings.

Acid mine drainage Wikipedia
Acid mine drainage, acid and metalliferous drainage (AMD), or acid rock drainage (ARD) is the outflow of acidic water from metal mines or coal mines.. Acid rock drainage occurs naturally within some environments as part of the rock weathering process but is exacerbated by large-scale earth disturbances characteristic of mining and other large construction activities, usually within rocks

EPA What is Acid Mine Drainage
What is Acid Mine Drainage Sources of Non-point Source Pollution Acid Mine Drainage (AMD) is currently the main pollutant of surface water in the mid-Atlantic region. AMD is caused when water flows over or through sulfur-bearing materials forming solutions of net acidity. AMD comes mainly from abandoned coal mines and currently active mining.

Construction of Dry Cover System for Prevention of Acid
The negative impacts on the nature of coal development by open cast mining have been reported with expansion of coal production recently in Indonesia. Acid Mine Drainage (AMD), which is a serious environmental problem, is attributable to the contact of sulfide minerals with water and oxygen in excavation activities in mining.
The Social and Environmental Consequences of Coal Mining
Open cast mining removes large volumes of soil and rock overburden to get to the workable coal seams, and destroys regional aquifers. Mining produces large mountains of solid waste. Coal heaps are prone to spontaneous combustion. Leachate from waste heaps are often acidic, adding to the general and large scale acid mine drainage
