· More specifically, mining is used to extract non-renewable resources like fossil fuels, minerals and even water. There are four main methods of mining: underground, surface, placer and in-situ. The type of mining method used depends on the kind of resource that is being targeted for extraction, the deposit’s location below or on the

· The underground mining for mineral exploitation comprises of mainly three stages viz. making access to the orebody, initial/box-cut excavation and final excavation of ore. The primary access to the underground mine is in the form of shaft, incline, decline or adit. These accesses are made from the surface.
