excess spoil from coal mining and surface mining

Excess Spoil Minimization and Fill Stability 1 and Mike

Excess Spoil Fills When coal is mined by surface mining methods, rock and soil that overlie the coal must be first temporarily removed and stored outside of the immediate mining area The rock is blasted as it is removed The angular blast rock, or “spoil,” incorporates voids and therefore is less dense than undisturbed rock Therefore, the

Surface Coal Mining and Reclamation Operations; Excess

Surface coal mining activities other than excess spoil fills may also involve disturbance of stream channels Coal deposits underlie many streams at shallow depths, and mining activities routinely divert and relocate a watercourse to remove the coal Underground mining development involves excavating rock and soil on the surface to expose the coal seam and to provide access for people

CHALLENGES TO APPLYING GEOMORPHIC AND STREAM

Some of the most contentious issues related to coal surface mine reclamation surround the practice of mountaintop coal mining in the steepslope topographic settings of Central Appalachia and the construction of excess spoil fills in valleys below the mine sites Chief among them include: the flattening of the ridge and valley landscape that often results; the burial and pollution of headwater

Environmental impact of mining Wikipedia

Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes These processes also have an impact on the atmosphere from the emissions of carbon which have

The Effects Of Surface Mining On The Environment

Per ton of coal, around twentyfive tons of overburden is excavated (“Surface Mining”) To remove overburden, one must blast through the hard cap rock which, in turn, leaves the landscape withering Normal organic matter is prevented from getting into the soil causing a loss in vegetation and a displacement of wildlife The lack of vegetation also increases the rate of erosion Mining
