Mining is being increasingly carried out underground as open pits near the end of their mining life and new ore bodies are increasingly being identified deep underground. Constructing underground mines with the use of conventional shaft and tunnel boring machines, however, has proved to be technically challenging, expensive and sluggish.
Underground specialized mining equipment such as trucks, loaders, diggers etc. are used to excavate the material and are normally hauled to the surface with skips or lifts for further processing. Drilling is normally required to place explosive charges to liberate the minerals from the overburden material.
