Robbins' close partnership with the mining industry spans decades, from non-circular prototype machines such as the Mobile Miner to early TBM usage in coal, copper, and gold mines worldwide. While those early machines were successful, modern machines are vastly more powerful and efficient than those tested and used in the 1970s and 1980s.
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 a pit, and the ...
But the truth is, modern-day coal mining is highly mechanized and it employs relatively few workers, many of them non-union. Consider the coal companies in the Powder River Basin that extract nearly 500 million tons of coal each year with just 7,000 workers.
