Basic Overview Of Mine Surveys

By Stacey Burt


Canada has a proactive policy in favor of this industries. It thus supported politically and financially by Canadian mining companies (such Anvil Mining (en), First Quantum Minerals) some of which exploit African soil and perpetrators of abuse (looting, expropriation, tax evasion, corruption) (mine surveys).

The copper mines of Iberian Peninsula were already 2500 BC. Chr. Developed by a Copper Age culture (Los Millares). From here the Bell Beaker people spread metallurgical skills in Europe. In ancient times, the silver mines of Laurion were famous. There slaves worked for the Athens citizens. The Romans exploited the old mines in Tartessos, in Britain and Dacia (Romania) and further developed in other provinces new.

Since the development and exploitation of mineral deposits is very time consuming and expensive, it is to have a high contract and investment security for mining companies of concern. This contrasts with the interests of state to achieve the highest taxes from mining. Customer and recipient countries want security of supply and low prices.

This preparatory work is often performed outside of mining sector, scientific agencies and authorities. By their visibility at the Earth's surface (outcrops) have been discovered - from prehistory to modern times, many deposits - for example veins. A future increasing importance of reduction of deposits in deep sea is obtained.

In mining industry is basically governed by the Federal Mining Act, similar legislation in other countries. The public authority is transferred regulatory control, ie mining office in Austria Mining Authority. In Switzerland, the mining law jurisdiction is at theThe oldest form of raw materials, which is referred to as mining, goes back to occasional use of flint deposits in Stone Age. Small working teams went for a few days flint mines to win a raw material for the manufacture of equipment.

In Stone Age cultures (North America, New Guinea), this operation held in part to present day. The exploitation of Mediterranean obsidian deposits is considered to be the work of opportunity miners. A permanent or seasonal mining operation requires an agricultural surpluses and trade, as the miners need to be fed, without being able to produce their own food and even produce more products than the community can use. The conditions were usually given only in Chalcolithic period (Naqada / copper mines of Timna in Egypt). Iran's copper mines are already stone age and over 6500 years old. The heyday of Cypriot mines begins 4000 years ago.

There were probably against 3000 v. Chr. Already ore mines in India and China. A 3000 v. Chr. Dated gold mine is currently in Georgia. Around 2500. Chr. Began copper mining in central Germany. Iron ore was mined from about 800 v. Chr. In Alps. In central Germany, a furnace from the La Tene period in Wilnsdorf testimony of mining to 500 sets v. Chr. From. The mining of coal has been known since the 9th century in England.

Basically, an infrastructure must be created in establishment of a mine regardless of type of raw material extraction, which allows the removal. If the mining area - as is often the case today - is in remote wilderness regions, already the construction of roads or railways and the creation of workers' settlements inevitably leads to a far-reaching influence on the natural environment. Experience shows that along the roads over time more plants of various kinds and thus new settlements and other roads arise, at least reinforce the parcelling of natural landscapes and habitat destruction, more and more.
