Underground mining method selection is one of the most important decisions that mining engineers have to make. Choosing a suitable underground mining method to extract a mineral deposit is very important in terms of economics, safety and productivity of mining operations.
Underhand cut and fill mining methods are used at the Lucky Friday, Stillwater, and Galena mines in the western US in an effort to safely mine in difficult ground conditions and as a primary mining method where access below the ore is limited. The method has evolved at each mine to meet the unique situations associated with their milling procedure

Underground Mining Methods presents the latest principles and techniques in use today. Reflecting the international and diverse nature of the industry, a series of mining case studies is presented covering the commodity range from iron ore to diamonds extracted by operations located in all corners of the world.
Room and pillar mining was one of the earliest methods used, although with significantly more manpower. The room and pillar system is used in mining coal, gypsum, iron, and uranium ores, particularly when found as manto or blanket deposits, stone and aggregates, talc, soda ash and potash.
The four methods are: chamber and pillar mining, sublevel stoping with spent shale backfill, sublevel stoping with full subsidence, and block caving using load haul dump (LHD). All more » mine designs were developed for 85,000 tons per day minimum production or enough feedstock for 50,000 barrel per day surface processing plant.

Feb 28, 2018· The method to be used for underground mining depends on the concentration of ore, strength of the surrounding rock, and the various risks involved. ScienceStruck explains what these methods are, with the applications of each one.
Mining Mining Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the ...
