14.3 Open Cast (Strip) Mining - 1of 2

mining or contour mining. Area mining is often referred to as open cast or strip (furrow) mining. It is frequently practiced on a large scale, which results in low unit cost, high productivity, high recovery, and greater safety compared to underground min-ing. Contour (or collar) mining progresses in

5 Chief Pros and Cons of Strip Mining – ConnectUS

29/08/2015  Usually, strip mining is employed in mining tar sand and coal. It’s a method referred to as open cast, open cut or stripping. First, the trees, shrubs and other structures in the area to be mined are removed – a task accomplished with heavy duty bulldozers. Holes are then drilled for the placement of explosives which are meant to loosen the overburden so that earthmoving equipment can easily

Strip mining, like other types of surface mining, finishes in hurting the area around the mine. The rock, gravel, trees, plants, and filth are dumped in regions round the mine. When it rains, this runs over the land and into watercourse and rivers. The rain pushes the mine filth on top of the region topsoil and buries it. The streams lands up being blocked and rivers flood. Water is impure by ...
