the impact of in pit crushing and conveying (ipcc) equipment on pit shell optimization is a key element that is often overlooked in the early stages of mine planning. most of the analysis typically completed regarding ipcc is on the potential for cost reduction, whether in an attempt to improve a project’s economics, or to extend mine life.
continuous mining systems bucket wheel excavator the bucket wheel excavator is the most powerful tool for mining in unconsolidated and soft rock and a precondition for a real continuous mining system. the bucket wheel excavator combines three parts of the mining process in one machine: extraction, loading and transportation to the conveyor.
mining of raw materials is a process that consists of several stages. in open-pit mining, material with high compressive strength is extracted by drilling and blasting and material with low compressive strength is extracted by e. g. a bucket wheel excavator. most important influencing factors for crusher decision are compressive strength, moisture content, capacity of crusher, abrasiveness

support the overlying rock, but in some mines, after mining has reached the deposit’s boundary, some or all of the pillars may be removed.’ on the face of it, quite a simple definition; however, room and pillar mining as practised in the narrow reef hard rock mines in southern africa is not so simple.
underground mining method is more selective than the surface mining method counterpart, but the degree of this selectivity depends on the underground mining technique employed , (hamrin, 2001).
surface rock support of underground mines code of practice 1.0 introduction rock falls are an ever-present hazard in underground mining, especially in unsupported ground. they are primarily caused by discontinuities and/or high or low adverse stresses in the rock mass. the intersection of three or more joints or fractures with the back, face or
