Price To Build A Coal Seam Mine

  • Coal Geology | Geoscience Australia

    Underground mining currently accounts for about 60 per cent of world coal production but around 80 per cent of Australia's coal is produced from opencut mines. Opencut mining is only economic when the coal seam(s) is near the sur face. It has the advantage of lower mining costs and it generally recovers a higher proportion of the coal deposit than underground mining, as most seams present

    Many of the thinner seam mines were unsuitable for mechanisation and the fairly high ash, sulphur or chlorine contents of lower coal measures seams meant that their coal was unacceptable to the large, coal-fired electricity stations. As a result a swathe of older, shallower West Yorkshire mines closed from the late 1960s and production was concentrated to the east of the M1. Many collieries

    Coal prices at surface mines are generally lower than prices at underground mines. In locations where coal beds are thick and near the surface, such as in Wyoming, mining costs and coal prices tend to be lower than in locations where the beds are thinner and deeper, such as in Appalachia. The higher cost of coal from underground mines reflects the more difficult mining conditions and the need

    In this mining strategy, seams of the coal are mined partially, leaving large pillars of coal intact in a bid to support the overlying layers of rock. When they are done, miners practice what is known as retreat mining. In retreat mining, they extract the maximum amount of coal they can from the remaining pillars on their way out, allowing the roof of the coal seam to collapse. Longwall Mining
