A surface gold mine wishes to develop a new pit (Pit A) as part of its mining schedules. The proposed pit outline is about 300 m to the closest community. Blasting operations in Pit A would potentially create undesirable environmental impacts including fly rocks, ground vibrations and air blasts to neighbouring communities. Integration of proper planning tools or protocols for blasting at Pit ...

Impacts of strip mining: Strip mining destroys landscapes, forests and wildlife habitats at the site of the mine when trees, plants, and topsoil are cleared from the mining area. This in turn leads to soil erosion and destruction of agricultural land. When rain washes the loosened top soil into streams, sediments pollute waterways.

The increase in leases for surface gold mining in Ghana between 1983 and 1998 has had drastic consequences for sustainable land use and management in the country. Most of these leases were for surface mining displacing the original owners from large arable land needed for their livelihoods. This situation makes the local people vulnerable to econom-ic uncertainties.

Considering the manifold impacts of gold surface mining on local livelihoods, it is perhaps not surprising that substantial land use conflicts have recently become apparent in Wassa West District (Lassey 2002). In the Bogoso-Prestea area, where many people depend on small-scale mining, violent conflicts between galamsey (i.e., small-scale miners) and security personnel of the mining enterprises occur frequently as we observed in 2006.

How Mining Methods Affect the Environment. There are many forms of mining depending on the resource being extracted. Each of these methods create types of pollution. Underground mining involves digging and tunneling to reach deep deposits like coal. Surface or strip mining removes surface vegetation and soil to exploit shallow deposits of coal.

The impact of mining is leading to the major issues, like a threat to the entire environment and also damaging the health of all life on Earth. Mining procedures generally require a larger and vast area of land. Deforestation is a by-product of mining and the build up of the mining areas requires constructing roads and residences for the mine employees and often vegetation farms are abolished.
