shaft system, so the mine engineerplanner must consider the entire mineral resource or potential to increase the resource at depth. Figure 1 depicts a typical access strategy for platinum mine where the initial orebody is exploited by means of an incline or decline shaft system, and later accessed by vertical shafts.Online Consulting
Shaft mining is a form of underground mining where shafts are pushed vertically from top to bottom to excavate the ores and minerals. It is also called shaft sinking. It is best suited for concentrated minerals such as iron, coal, etc. which can be found at the depth of the earths surface.Online Consulting
