Environmental Effects of the Open Cast Mining a Case

2015-7-3  Most of the mining operation is (Sammad area) mainly open cast mining. The mining activities emit air pollutants such as particulate matter (PM) into the air through different sources and emissions. The mining activities have fugitive dust sources that contribute to in- creasing air quality levels in the urban areas around the quarries.

EFFECTS OF OPEN-CAST SULPHUR MINING ON

mining for Pb, Zn, Cu, Cd and Fe is of widespread international concern, as pollution resulting from metal mining activities can result in significant environmental and ecological degradation and can pose serious risks to human health through con-tamination of food and drinking water (Byrne et al. 2012). Herr and Gray (1996), for instance, assessed

Sulphur-rich minerals such as authigenic pyrite (FeS2) are commonly associated with coal mine workings. Metallic elements such as arsenic (As), copper (Cu) and zinc (Zn) are enriched in the pyrite relative to their concentrations in the surrounding environment. Exposure of pyrite and coal to air and water results in a series of oxidation and hydrolysis reactions that are commonly catalysed by ...

The paper is limited to open-cast areas in Northumberland, Durham and the West Riding of Yorkshire and is largely concerned with the soil aspect of the problem. Restoration of a site to agriculture is planned on a 5-year basis and includes a summer fallow and a grazing ley. The initial crop is usually wheat, followed by more wheat, then by barley undersown with grass.
