Underground mining is used for gold, platinum, zinc, lead, and increasingly, coal. As can be seen, surface mining is much more advantageous than its counterpart. However, when an outcropping ore body stretches deep inside the Earth, surface methods can be used to begin the mining operation, which then need to be continued further by underground

Zinc ores are obtained by many mining techniques, ranging from open-pit mining to the normal underground methods. The most common underground method of ore extraction is cut-and-fill stopping, in which tunnels are dug to moderate depths, branching away from the mine holes.
Underground rooms had walls 25 to 100 feet high and pillars 20 to 50 feet thick. In areas around the town of Galena, where the ore was not very deep, however, surface mining was more common. The area became known as a poor man's mining district because small claims could be easily worked without much equipment.
Zinc ore is usually is found in association with those of lead, copper, gold, silver as well as other metals. Zinc is found in igneous and metamorphic rocks which usually are underground, so zinc mining is often underground but some new mines are of the open pit type.
Rampura Agucha mine is the world’s one of the largest zinc mine. It has an ore production capacity of 6.15 million MT per annum, with best-in-class zinc-lead reserves grade of 15.8%. It produced 528,459 MT of mined metal in the year FY 2017. Reserve and resource of Rampura Agucha Mine as on 31st March 2017 are 100 million MT.

In 1966, the New Jersey Zinc Company became part of Gulf + Western Industries, Incorporated and became the largest miner of zinc ore in the United States, using the horse head as its logo. By the late 1970’s, Austinville had ceased underground mining due to a reduction of the lead market and improved Environmental Protection Agency standards.
Tara Mines is a zinc and lead mine near Navan, County Meath, Ireland.Tara is an underground mine where the orebody lies between 50 and 900 metres below the surface in carbonate-hosted lead-zinc ore deposits.. The deposit was discovered in 1970 by Derek Michael Romer while working for Pat Hughes' Northgate Exploration.
The Rampura Agucha open-pit lead zinc mine is producing 5.7 Mt/a of ore and has started its underground part, which is slated to produce initially 2–2.4 Mt/a and 4.5 Mt/a in the near future.
Surface mining is a form of mining in which the soil and the rock covering the mineral deposits are removed. It is the other way of underground mining, in which the overlying rock is left behind, and the required mineral deposits are removed through shafts or tunnels.. Surface mining is basically employed when deposits of commercially viable minerals or rock are found closer to the surface
Mining Methods, Surface mining Depend on wa ter or another liquid (e.g., dilute sulfuric acid, weak cyanide solution, or ammonium c arbonate) to e xtract the miner al.
UNDERGROUND MINING. Rob Parr was originally an underground mining engineer and progressed through the ranks to manager level. Rob has over 14 years experience in commodities such as gold, uranium, nickel, copper, silver, lead and zinc. Rob also has experience in all types of mining methods from narrow vein gold to block caving. VIEW OUR RECENT

Uses of Zinc. Sterling Hill was a zinc mine, and the last operating underground mine in the State of New Jersey. It closed in 1986 after more than 138 years of almost continuous production, during which it yielded more than 11 million tons of zinc ore. The ore was fabulously rich, averaging more than 20% zinc, and occurred in thick seams that were worked to a depth of 2,550 ft below the
Zinc ores are recovered by many mining techniques, ranging from open-pit mining mainly in the case of oxidized ore bodies, which are located closer to Earths surface to the normal underground methods used for the more deeply located sulfide ores. The most common underground method of ore extraction is cut-and-fill stoping, in which. Read More >

Zinkgruvan is an underground mine with a long history having been in continuous production since 1857. The operation is comprised of an underground mine, a processing plant and associated infrastructure, producing zinc, lead and copper concentrates. Lundin Mining acquired the mine
Mining for Copper & Zinc Surface exploration at AMAK continued through the 1960’s and 70’s and was augmented from 1978 to 1980 with an underground exploration campaign.This consisted of the decline from the current surface Portal to 1515 Level, and an exploration drive along 1515 Level North to Sa’daah and South to the Al Houra []

6.1.1 Lead and Zinc Ore Mining Lead and zinc ore is nearly always mined below the surface of the ground. Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface. Lead and zinc ore is mined almost exclusively in underground operations, though a few surface operations do exist.

Depending on how these ores are extracted, mining methods can be categorized as ‘surface’ or ‘underground’ types. In surface mining, the rock barrier on top of the deposit is removed to access the ore. However, sometimes, such deposits occur too far below to access them from the surface.
Newtrax Technologies. Founded in 2008, Newtrax Technologies believes the future of mining is underground, not only because metals and minerals close to the surface are increasingly rare, but because underground mines have a significantly lower environmental footprint.
Mining on the ABM deposit would be conducted via open-pit and underground mining methods, with mineralized material processed into separate copper, lead and zinc concentrates at a 2-million-tonne
