Summary The open-pit method for developing mineral deposits is one of the leading methods for obtaining ore and non-metallic raw materials. Its use in mining contributes to the activation of various processes that transform the geological environment, often causing irreversible changes in the properties and characteristics of all its components.

2008-8-26 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 open-pit mining in particular. As such, a repeatable process to evaluate these effects primarily aims to diminish them. This paper ...

2017-3-28 Surface mining or open-pit mining depends on the removal of all surface soil and rock covering the desired Uranium. While it is safer for the miners than underground mines since they are not exposed to roof-falls or pneumoconiosis, it blasts 30 times more topsoil than Uranium ore and the resulting land is left with radioactive, toxic elements ...

2020-8-21 Mineral exploitation contributes significantly to economic growth and development in most world economies. In Africa, Ghana is the second largest gold producer, contributing to about 5.7% of the country’s GDP. The mining sector in Ghana consists of both small-scale and large-scale mining, each of which has varying environmental impacts. This paper provides an exposition on the environmental ...

2021-6-8 The proposed mining method for the operation is a small retreating open pit, which in itself has proven environmentally friendly, in sharp contrast to dredging or strip mining. Usually, small retreating open pit involves the opening of one side through digging ores and supplying them to the process plant.

2021-11-4 Open Pit Mining. Open pit mining is similar to area mining. The technique is common in the western United States (and other parts of the world) where very thick — 50 to 100 foot — coal seams exist. Open pit mines are usually large operations. Production levels may exceed 10 million tons of coal per year.. The thick coal seams found at these large mines ensure that the amount of land ...
