NSW mines and other solutions, for example surface temperature control by water jacketing and other methods, to reduce the occurrence of fires on mobile plant. You are invited to respond to some or all the questions posed in this discussion paper and provide any immortal eyes the toy box pdf Surface mining is often preferred to sub-surface (underground mining) by mining companies for several reasons. It is less expensive, there are fewer complications in terms of electricity and water and it is safer. However, surface mining can be environmentally more damaging than subsurface mining.

Box Cut In Surface Mining Pdf
In coal mining: Area strip mining …with a trench or “box cut” made through the overburden to expose a portion of the coal seam. This trench is extended to the limits of the property in the strike direction.
- Surface mining in which reclamation is carried out contem-poraneously with extraction may be classified as either area 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
