The mine adit was made 1927 1930 by the coal mining company Bj#248;rn#248;en A/S, and tonnes of pure lead sulfide (galena) ore was shipped from this mine. Photo: Tom V. Segalstad, 4 July 2000. A first period of exploration in the early part of the 20 th Century resulted in the limited exploitation of several deposits, chiefly for lead ore (Picture 2).
Define adit. adit synonyms, adit pronunciation, adit translation, (Mining amp; Quarrying) an almost horizontal shaft into a mine, mine excavation in the earth from which ores and minerals are extracted. passage a way through or along which someone or something may pass.
An adit (from Latin aditus, entrance) is an entrance to an underground mine which is horizontal or nearly horizontal, by which the mine can be entered, drained of water, ventilated, and minerals extracted at the lowest convenient level. Adits are also used to explore for mineral veins. Contact US Adit Tunnel Mining Royal Rajasthan on Wheels
While mining provides us with the minerals we need, it is also very destructive because it disrupts the landscape both on the surface and underground. It also causes quite a bit of pollution and
Since Adit mining take place horizontally, air current could easily enter the mine. Advantages distributed into society: Since most mineral are very valuable, mining bring a very good sum of money to society through the employment of loweducated people (miner doesnt require much education, however mining is old require strength and

Adit method: This is when the mineral lies deep underneath and side tunnels are used to mine it. Some are mined through open cast method if they are found near the surface as part of the rock. Mining of selected minerals in Africa . Petroleum mining in Nigeria.
Mining is the extraction of valuable minerals or other geological materials from the earth from an orebody, lode, vein, seam, or reef, which forms the mineralized package of economic interest to the miner.. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain any material that cannot

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 diamonds or rubies. Soft rock mining refers to excavation of softer minerals such as salt, coal, or oil sands.
Introduction to Adit Mining Adit mining is a method of extract minerals from earth horizontally. An adit is a type of entrance to an underground mine which is horizontal or nearly horizontal. Adits are usually built into the side of a hill or Mountain, and often occur when a measure of coal or an ore body is located inside the mountain but above the adjacent valley floor or coastal plain.
An adit (from Latin aditus, entrance) is an entrance to an underground mine which is horizontal or nearly horizontal, by which the mine can be entered, drained of water, ventilated, and minerals extracted at the lowest convenient level. Adits are also used to explore for mineral veins.
Underground mining is used to extract ore from below the surface of the earth safely, economically and with as little waste as possible. The entry from the surface to an underground mine may be through a horizontal or vertical tunnel, known as an adit, shaft or decline. Underground mining is practical when:
Surface mining is both the less expensive of the two and the goto method when the desired minerals are located near the surface of the Earth. Whether its with the aid of explosives or heavy excavation equipment, the topsoil is removed to reach the buried treasures, most commonly in the form of openpit and strip mines, mountaintop removal, and quarrying, according to GreatMining .
Where either a vertical shaft or an adit can be used to reach a mineral deposit, the generally lower cost of driving an adit, the saving in the cost of pumping water, and the ease of hoisting ore through the shaft dictate in favour of the adit. Consequently, adits as long as one to three kilometres (one or two miles) are often economically feasible.
