LONG-TERM EFFECTS OF SURFACE COAL MINING ON

2011-2-8  Few analytical data are available on the long-term effects of surface mining on the ground-water hydrology of small watersheds. Some hydrologic processes necessary to evaluate long-term effects are not fully understood. These processes include the changes in hydraulic head and ground-water quality resulting from mining and the time required

Long-term effects of surface coal mining on ground

Surface mining removed the upper aquifer, stripped the coal seam, and replaced the sediment. This created a new upper aquifer with different hydraulic and chemical characteristics. Mining did not disturb the middle aquifer. A third, deeper aquifer in each watershed was not studied. Water levels were continuously recorded in one well in each aquifer.

Effects of coal mining on ground and surface water

Water quality data are compared. Areas disturbed extensively either by surface or underground mining for bituminous coal in Monongalia County, West Virginia yield water of poorer quality than similar terrain which is not so disturbed. Specifically, the disturbed areas yield hard water of the calcium-sulfate or calcium-magnesium-sulfate type which ...

Effects of iron mining on surface water quality in the ...

Iron mining in the Schefferville, Quebec, area has resulted in the disruption of some small surface drainage systems and the discharge of large amounts of pumped groundwater into them. Major ion concentrations in surface waters is controlled by the occurrence of the Denault (dolomite) formation, and little change is caused by the mining activities.

Effects of mining activities on evolution of water

The results of hydrochemistry and isotopic composition indicate that the regional surface water and partial karst groundwater are obviously affected by coal-mining activities, which is mainly manifested in the increase of water solute concentration and the change of hydrochemical types.

Long-term effects of surface coal mining on ground

Two small watersheds in eastern Ohio that were surface mined for coal and reclaimed were studied during 1986-89. Water-level and water-quality data were compared with similar data collected during previous investigations conducted during 1976-83 to determine long-term effects of surface mining on the hydrologic system. Before mining, the watersheds were characterized by sequences of flat-lying ...

EFFECTS OF SURFACE COAL MINING AND RECLAMATION

2010-12-17  The effects of surface mining on ground water have been a matter of concern ever since surface mining became widespread around the middle of the twentieth century. Ground-water quality is of major concern because it is a primary determinant of the water quality of base flow in streams, and
