treatment of coal tailings the coal handbook towards

Chapter 4 - GARDGuide

Issues such as reduced mine footprint, ARD prevention in waste rock and tailings (and coal refuse), and the avoidance of long-term water treatment should be integrated into the mine design to ensure that the economic model for mine development fully considers the true costs of the whole lifecycle, including post-closure.

Coal mining has major impacts on terrestrial and aquatic ecosystems. In many cases, whole mountaintops are removed for coal extraction, and valleys are filled in with the waste rock (tailings). Whether it is mountain-top removal, open-pit, or underground mining, however, a major problems stems from rain filtering through the coal mine and tailings.
