Coal mining activities were generally well documented and detailed plans would have been produced in most cases. County or national archives may hold copies of large-scale plans and sections that would indicate where colliery waste was disposed. Walkover. The walkover should consider how the surface morphology reflects the underlying material.

Unfazed, the mining operation simply steered around their land, and dumped a mountain's worth of rocky debris into the Laurel Branch up to their property line. When mountains are demolished with explosives to harvest their coal seams, the millions of tons of crushed shale, sandstone, and coal detritus. Photo Gallery.

Polycyclic aromatic hydrocarbons (PAHs) and potentially toxic elements (PTEs) (Ba, Zn, Pb, Cu, Cr, Ni, As, Co) were determined in the road dusts of a coal mining area (Dhanbad, India) to assess their content and potential human health risks. Dust samples were collected from sign boards of the heavy traffic road connecting Dhanbad …

Coal mining areas are prone to hazardous element contamination because of mining activities and the resulting wastes, mainly including Cr, Ni, Cu, Zn, Cd and Pb. This study collected 103 samples of farmland tillage soil surrounding a coal mine in southwestern Shandong province and monitored the heavy metal concentrations of each …

In China, coal provides about 56.8% of the energy. Most of China's coal mines are shaft mines, which cause the surface to collapse and crack during the mining process. The soil near the cracks changes its physicochemical properties due to the altered stress conditions. This will affect the distribution of PTEs in the soil. We collected 18 …

By Mike Ives • January 28, 2013. In November, the first shipment of raw "rare earth" minerals arrived at an $800 million processing plant on Malaysia's east coast near the home of Tan Bun Teet.
