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

McKinsey Metals & Mining published a 2015 stone that predicted a technology-enabled transformation of the mining industry. The stone identified some potentially game-changing innovations that we believed would revolutionize the way mines operate and deliver much-needed productivity gains.
One of the themes of Donald Trump’s presidential campaign was bringing back coal stone to the Midwest. As president, he has doubled down on this, promising to “lift restrictions on American energy — including shale oil, natural gas and beautiful, clean coal.”[1] Many Republicans have blamed environmental regulations enacted during the Obama administration for the decline of the

Starting from a position of strength is a good thing. Northern Ontario, and in particular the Greater Sudbury Area, has an emerging underground mining technology cluster that is a global powerhouse. Indeed, it could be said that the Greater Sudbury Area is the Silicon Valley of mining technology
1. Introduction. Intelligent mining, which is based on mechanized and automatic mining methods and which combines informatization with industrialization, has brought about a revolution in the coal industry .This new technology can carry out mining automatically by intelligently perceiving the circumstances around the work face, intelligently controlling each mining machine, and automatically
Surface Coal Mining Methods in Australia 9 specially designed computer system provides precise control over the bucket, enabling the dragline to dig and dump anywhere under the boom (Mining Technology Australia, 2011). This was developed in conjunction
In 2008, competition in the coal mining industry became more intense than ever, leading to a demand for better technology and new mines. History of Mining Technology. In the beginning, miners used primitive tools for digging. Mining shafts were dug out by hand or using stone tools, making the entire process very lengthy.
Technological advancements have made coal mining today more productive than it has ever been. To keep up with technology and to extract coal as efficiently as possible, modern mining personnel must be highly skilled and well-trained in the use of complex, state-of-the-art equipment.
