Get PriceSo, the cut and fill process is typically one of the first construction processes to take place on a site. Without computer software to determine the amount of land to be added or removed, we can do simple calculations to estimate the cut and fill volume of any site. First, the site is divided into sections.

Get PriceThis method can be used in wider deposits, as well, by drilling two adjacent access ramps and cutting two adjacent drifts, often called drift and fill . Cut and fill is for hard rock, as it doesn't feature the support mechanisms inherent in and central to a method like room and pillar.
Get PriceDry rock fill is rock waste, surface sands, gravels, or dried tailings. The fill is either dropped down a raise, or tipped into an open stope by a Load Haul Dump (LHD) or dump trucks. Dry rock fill is most suited for the cut and fill mining method.
Get PriceIron ore is almost exclusively mined by surface operations. The most predominant surface mining methods used for mining of iron ores are open pit mining methods and open cut mining methods. However a few underground iron ore mines are also in operation around the globe. How iron is made material, manufacture, making, history

Get PriceThe Mining of Iron Ore. Iron ore mining was a thriving industry in many parts of the world, with the smelters being located as close to the mines as possible. However as larger mines where more efficient mining of higher iron content ore became effective, the smaller mines fell by the wayside.
Get PriceCut-and-fill mining methods at the Thompson Mine have undergone significant changes since production began in 1961. Changes have been introduced in almost all aspects of the mining operation, from the original timbered chutes and air-operated slushers to the present-day bored raises, footwall ore passes and load-haul-dump units.This paper describes the evolution of mechanized cut-and-fill
