Impact of Mining on Ground and Surface Waters By H.N. KARMAKAR1 P One of the major effects of mining is its impact on ground and surface waters. This along with other disturbances make the ecosystem to meet with grevious consequences. The impact of mining on ground water may be considered under the fo11owing areas a Lowering of water table

Changes of Water Quality in a Stream Impacted by Longwall Mining Subsidence Jankowski algal blooms Krogh 2007. The occurrence of metal precipitates and iron-oxidising bacteria is particularly evident in creeks and rivers where groundwater interacts with surface water and discharges through riverbed and rockbar cracks TEC 2007
Mining and pyrite oxidation have polluted the water in old mines and this pollution has reached ground water reservoirs. The ceilings of the shafts located at a depth of 1050 m keep collapsing leaving the Earths surface with terraces and holes
Surface and groundwater samples within the catchment area of the Obuasi mine were analysed to assess the impact of mining activities on water resources. The concentration of Fe Mn Cu Zn Pb Cd Hg As and selected major ions in water samples were analysed to assess their role in the contamination of both surface and ground water
Since longwall mining causes subsidence through the overlying strata to the ground surface the surface water and groundwater above the longwall panels may be affected and drained into the lower levels. Therefore loss or interruption of streams and overburden aquifers is a common concern in coal industry. This paper analyed the potential effects of longwall mining on subsurface water system
2020-4-4ADVERTISEMENTS The Impact of Surface and Coal Mining on Environment Surface mining often leads to acid mine -drainage and silt run off which degrades quality of water. Acid mine drainage is an important source of increased acidity in natural waters. Its main constituents are sulphuric acid and iron compounds formed as a result of water

The leachate samples were taken at the end of February 2014 while the surface and ground water samples were taken in intervals April 2013 September 2013 and February 2014. In order to de-termine leachate characteristics with different stage of decomposition the samples were taken from different lo
2014-9-17LGUs often lack the expertise to assess ground-water models Southwick and others 2000. . Quarries and pits can affect ground-water and surface-water systems in various ways. This project focused on the following potential impacts lowering of local ground-water and surface-water levels from mining operations and mine dewatering
2015-12-10Mining activities can also impact deep ground waters that may supply wells and drinking water systems. Processing ore to remove the REE typically uses water that must then enter a waste water stream to be contained or reused. A proper waste water system is a critical aspect of most mining
2020-3-31Due to its unique properties water is of multiple uses for all living organisms. Water is absolutely essential for life. Most of the life processes take place in water present in the human body. Human beings depend on water for almost every developmental activity. Water is used for drinking irrigation and transportation washing and waste

2013-10-2Mining impacts both surface waters and groundwater. In under-ground mining waste materials are piled at the surface creating runoff that both pollutes and alters the flow of local streams. As rain percolates through these piles soluble components are dissolved in the runoff and cause the elevation of total dissolved solids TDS in local
2020-5-19Mining can have adverse effects on surrounding surface and groundwater if protective measures are not taken. The result can be unnaturally high concentrations of some chemicals such as arsenic sulfuric acid and mercury over a significant area of surface or subsurface. 3 Runoff of mere soil or rock debris -although non-toxic- also devastates the surrounding vegetation
Predicting the impact of mining on ground and surface water quality - sequential leaching tests. ChemCentres sequential leaching tests have been developed to identify chemical risks to the environment from potential contaminants due to the migration of metals and elements at mines into ground and surface water sources

It follows that the ground- water contamination potential of proposed practices cannot be observed with short-term field experiments. Nonetheless preliminary effects of

Despite the new emphasis placed on ground water by regulatory authorities the effects of coal mining on ground water are still poorly understood. It is the
Surface water and groundwater samples were collected from 20 locations situated in the vicinity of the abandoned coal mine fields south of Bochum. The main objective of this research is to assess the environmental impacts of these mines on the surface water and groundwater quality as well as to determine the factors controlling these impacts
