Underground mining methods are the focus of this article. The selection of a mining method for an ore deposit is based on many factors that are driven by the economics and profitability of the mine for a company. These include the following: Ore grade and recovery. Cost of infrastructure.stoping, cut-and-fill, longwall mining, sublevel caving, and block caving. The second section describes underground mining equipment, with particular focus on excavation machinery such as boomheaders, coal cutters, continuous miners and shearers. 1.
