Campaign mining setup for waste stripping at New Vaal Colliery by PR Mothemela* and K Chabedi* Paper written on project work carried out in partial fulfilment of BSc Eng (Mining) Synopsis The objective of the investigation is to optimize the truck and shovel operations for prestripping at New Vaal Colliery by introducing campaign miningAndrew P Schissler, in Encyclopedia of Energy, 2004 23 Strip Mining Strip mining is employed in coal reserves where the overburden is removed in rectangular blocks in plan view called pits or strips The pits are parallel and adjacent to each other Strip mining is fundamentally different from contour or area mining on how the overburden is displaced, called spoil handlingStrip Mining an overview | ScienceDirect Topics

Stripping Costs in the Production Phase of a Surface Mine

1 In surface mining operations, entities may find it necessary to remove mine waste materials (‘overburden’) to gain access to mineral ore deposits This waste removal activity is known as ‘stripping’ 2 During the development phase of the mine (before production begins), stripping costs are usually4 The material removed when stripping in the production phase will not necessarily be 100 per cent waste; often it will be a combination of ore and waste The ratio of ore to waste can range from uneconomic low grade to profitable high grade Removal of material with a low ratio of ore to waste may produce some usable material, which can be used toStripping Costs in the Production Phase of a Surface Mine

Understanding When Costs Associated with Overburden

Most opencast mines require the removal of overburden and waste material to access the underlying orebody This activity is known as ‘stripping’ By their nature, all open pits become narrower with depth, and consequently the volume of waste to be stripped is largest on the upper benches that must be mined first The problem is []The maximum allowable Stripping Ratio (SR max) defines break even stripping ratio (BESR)This represents the highest possible units of waste that can be handled If the SR exceeds the BESR then the operation will be uneconomical as the income generated by the ore is insufficient to offset the costs incurred in miningDetermining Stripping Ratio Basic Mining Techniques

Chapter 4: Mining waste SGU

The amount of waste rock that needs to be removed depends on the geometry and location of the ore body, mining method and the composition and stability of the bedrock The ratio of waste rock/ore is called stripping ratio For example, a stripping ratio of 2:1 means that 2 tonnes of waste rock needs to be removed to mine 1 tonne of oreCampaign mining setup for waste stripping at New Vaal Colliery by PR Mothemela* and K Chabedi* Paper written on project work carried out in partial fulfilment of BSc Eng (Mining) Synopsis The objective of the investigation is to optimize the truck and shovel operations for prestripping at New Vaal Colliery by introducing campaign miningCampaign mining setup for waste stripping at New Vaal
