Aug 26, 2008· Mining is widely regarded as having adverse effects on environment of both magnitude and diversity. Some of these effects include erosion, formation of sinkhole, biodiversity loss and contamination of groundwater by chemical from the mining process in general and openpit mining in particular. As such, a repeatable process to evaluate these effects primarily aims to diminish them.

Opencast coal mining: process and method Opencast mining, a method of mining introduced in 1942 to maintain coal supplies du ring the Second World War, is a quarrying method that is viable where a coal seam is relatively near the land surface or where a pit can expose a number of seams within an acceptable depth (normally up to 100m in the UK).
OBJECTIVES To answer the question whether living near opencast coal mining sites affects acute and chronic respiratory health. METHODS All 4860 children aged 1–11 from five socioeconomically matched pairs of communities close to active opencast sites and control sites away from them were selected. Exposure was assessed by concentrations of particulate matter with aerodynamic diameter <10 μm ...
