Openpit mining – General Overview. Openpit mining (also known as opencut mining or opencast mining) is a type of strip mining in which the ore deposit extends very deep in the ground, necessitating the removal of layer upon layer of overburden and ore. An ore is a type of rock that contains minerals with important elements including metals.
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 ...
two main methods Surface or 'opencast' and underground mining method. Geological condition determines the method of mining. Coal mining is usually associated with degradation of natural resources and destruction of habitat. This causes invasive species to occupy the area, thus posing a threat to biodiversity.
IMPACT OF MINING ON ENVIRONMENT Day by day as the mining activity increases it gives a huge impact on our environment. The impact of mining is on all the natural resources which can possess the effect on human as well as on wild life. The effect of mining activities are on soil, water, air, wild life, social values, and on climate conditions.

is manganese extracted by opencast mining. There is one operational manganese ore mine in Ghana, Nsuta Tarkwa, which is located at Tarkwa Banso in the Western Region, utilising an opencast, strip mining method. In 2006 the mine produced tonnes, of which 52% was exported to Ukraine, 37% to China, and the remainder to Norway.
Most walls of the pit are normally dug on an angle less than vertical, to avert and lessen damage and hazard from rock falls. This relies on how weathered the rocks are, and the kind of rock, and also how a lot of structural weaknesses happen within the rocks, like a fault, shears, joints or foliations.
