    This bulk underground mining method involves mining large amounts of material from a single stope similar to cut and fill, this method starts at the bottom of a level and moves upward. Ore is removed from the bottom, and then more ore is blasted from a higher level that falls to the same level to be removed, with the process repeating up the orebody.

  • Underground Mining Methods and Equipment

    The selection of underground mining methods is primarily based on the geological/spatial setting of the deposit. Candidate methods can therefore be chosen and ranked based on estimated operational/capital costs, production rates, avaiility of ors and materials/equipments, and environmental considerations. The method offering the most reasonable and optimized combination of safe ty

    Hard Rock MiningHard rock mining is a kind of underground mining. With this kind, an opening ismade that is called an adit.Tunnels into the ground are dug, blasted with dynamite, or drilled out. Thesetunnels are called shafts. Shafts are dug straight down vertically into theground. Each shaft has a purpose. One shaft might be for miners to use to go inand out of the mine. One shaft might be

  • Mining Wikipedia

    Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.

    By the New Stone Age,humans had progressed to underground mining in systematic openings 2 to 3 ft (0.6 to 0.9 m) in height and more than 30 ft (9m) in depth (Stoces,1954). However,the oldest known underground mine,a hematite mine at Bomvu Ridge,Swaziland(Gregory,1980),is from the Old Stone Age and believed to be about 40,000 years old. Early miners employed crude methods of ground

  • The Actual Difference Between Surface and Underground

    Underground mining is used for small, high-grade deposits covered with a thick overburden (soil and rock above the ore), or for deep and sloping deposits. General Process. In all methods of surface mining, first, the overburden is stripped off using earthmovers. Then, bucket-wheel s remove the ore, which is loaded into haul trucks with shovel loaders. When the deposit is exhausted

  • Underground mining (hard rock) Wikipedia

    Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals, usually those containing metals such as ore containing gold, silver, iron, copper, zinc, nickel, tin and lead, but also involves using the same techniques for excavating ores of gems such as s or rubies. Soft rock mining refers to excavation of softer minerals such as salt, coal
