Surface mining disadvantages: The removal of vegetation in soil, topsoil erosion, habitat loss, and increase stream trubidity. Surface mining advantages: It has lower finance cost and it is a lot safer than underground mining. Open pit mining disadvantages: Soil erosion, pollution, Habitat loss, Similar to surface mining disadvantages.
Open-pit mining, or opencast mining, is a surface mining technique used for large-scale operations. It involves extracting minerals from a pit by removing waste rock and overburden. Commonly used for minerals like copper, gold, and iron ore, requires heavy equipment such as trucks and shovels to efficiently extract the ore.
