With global demand for coal widely expected to rise over the next 20 years, Dr Gareth Evans finds out how a range of new technologies will help the coal mining industry meet that need - from both existing …
State-run miner Coal India plans to bid for three blocks in a critical minerals auction set for this month, chairman and managing director P.M. Prasad told reporters and analysts in a post-earnings conference call on Monday.. India launched the first part of its critical minerals auction in November last year, expecting to raise an estimated Rs450bn …
In the 18 th and 19 th centuries coal was used extensively to propel nations forward into industrial modernity. The inorganic mineral catalysed Promethean advancements: it powered the steamship and locomotive, and it enabled the construction of gravity-defying bridges with iron and the use of 'dark satanic mills' to accelerate cotton …

According to think tank Ember's 2022 report entitled Tackling Australia's Coal Mine Methane Problem, Australia's coal mines produce twice as much methane as official estimates. Australia joined a group of 120 countries signing the Global Methane Pledge to collectively reduce methane emissions by at least 30% from 2020 levels by 2030.
This study indicates that a canopy air curtain system can be designed to greatly reduce an operator's exposure to respirable dust by providing clean air to the operator, as the majority of the operator's dust exposure occurs in air velocities slower than 61 m/min (200 fpm).
In the eld of shallow coal mining theory and technology in China, Feng et al.4,35–37 have conducted a sig- nicant amount of targeted research and achieved remarkable results. Feng et al 4 ...
Intelligent and ecological coal mining technology. As one of primary energy sources, ecological coal mining not only copes with the physical environmental change to ensure the resource mining activities completed smoothly but also focuses on reduction of the adverse impact on the ecological environment. Over a dozen years high …
However, producing and using coal affects the environment. Effects of coal mining. Surface mines (sometimes called strip mines) were the source of about 63% of the coal mined in the United States in 2022.
