Coal in South Africa Wikipedia

South Africa produces in excess of 255 million most from witbank tonnes of coal (2011 estimate) and consumes almost three quarters of that domestically. Around 77% of South Africa's energy needs are directly derived from coal and 92% of coal consumed on the African continent is produced in South Africa.. The use of coal in South Africa dates back to the Iron Age (300–1880 AD), when charcoal

Coal mining Wikipedia

Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is a 'pit', and

SOUTH AFRICAN COAL SECTOR REPORT Department of Energy

The most economical method of coal extraction from coal seams depends on the depth and quality of the seams, as well as the geology and environmental factors. Surface (opencast) mining and deep underground mining are the two basic methods of mining used in South Africa. Approximately 51% of South African coal mining is done underground and

What are the main methods of mining? American

There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
