under the influence of one of the biggest Cu mines in the world: the Erdenet mine, located in North Central Mongolia. The results show that the Khangal River is suffering the influence of the mining works and waste accumulations of the Erdenet Cu mine.

Surface mining inevitably produces major environmental disturbances since vegetation, top soil and underlying soil mantle have to be removed to gain access to the minerals beneath. In underground mining, large quantities of waste are produced, which commonly exceed the volume of minerals (Plumlee et al., 1993; Salomons, 1995; Younger, 1997).
Dr. Abhay Kumar Singh is presently working as a Senior Scientist in the Water Resources Management Group at CSIR-Central Institute of Mining and Fuel Research, Dhanbad, India. He joined this institute in 1999 as a Scientist 'B' and was involved in several projects sponsored by mining industries pertaining to sustainable mining and management of …
The mining industry, especially coal mining, may severely affect the spatial and temporal evolution of groundwater. To provide a potential model outlining the hydrogeochemical evolution of groundwater as influenced by coal mining, a multi-layer groundwater system in a coal mining area was investigated. A total of 76 groundwater …
1. Introduction. The processes governing the production and transport of acid mine drainage (AMD) and drainage from unmined but mineralized areas are numerous …
The extraction of mineral resources requires access through underground workings, or open pit operations, or through drillholes for solution mining. Additionally, mineral processing can generate large quantities of waste, including mill tailings, waste rock and refinery wastes, heap leach pads, and slag. Thus, through mining and mineral …
Abstract The Sanggok mine used to be one of the largest lead-zinc mines in the Hwanggangri mining district, Republic of Korea. The present study characterizes the heavy metal contamination in the abandoned Sanggok mine creek on the basis of physico-chemical properties of various kinds of water samples (mine, surface and groundwater). …

Mine drainage samples are Ca 2+ –SO 4 2− type waters, except for sample M-1 (from near the adit mouth), which is a Ca 2+ –HCO 3 – type water. Mine drainage samples M-1 to M-14 from old mine workings has lower pH and higher EC values than river water, indicating significant impact of AMD on groundwater quality.
