Basic Guide To Mine Surveys

By Stacey Burt


The most well known copper mining area in Europe is that of Mitterberg in Salzburg. There was in late 2nd millennium BC. Chr. 32 mines. Calculations showed that this same 200 miners, steel workers and support staff must have served. Dissolving the ore from the pit wall by the rock was heated and quenched with water. The Bronze Age shafts were up to 100 m long (mine surveys). The chalcopyrite ore was succeeded in carrying baskets from the mine. For ventilation shafts ensured that linked the superposed studs together. Ladders made of tree trunks with tread grooves allowed the miners access to tunnel.

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.

There are over and underground mining method for solid, liquid and gaseous materials. Mining activities are regulated worldwide in respective mining law within national legislation. The degraded natural resources are located in a reservoir, the extent and location is now usually investigated by geophysical exploration.

This industry, in context of globalization and while some sectors are already facing an increasingly scarce resource must meet multiple demands and sometimes contradictory; a short-term benefit of demand, the shareholders and the markets, an increasing demand for material from particular manufacturers, the energy sector (coal ..) and construction including an application for the principles of sustainability development and geostrategic balances.

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.

One example is the 200-mile zone called by coastal States. Successful cross-border conflict rules such as the European Coal and Steel Community (as a forerunner of EU), the North Sea oil or the Svalbard Treaty established a stable basis for international cooperation.

Environmental and economic upheavals by means of mines are occupied early. From Middle Ages to modern times it has a lot of customers from so-called "silver rush". Halden and smelting in vicinity of mines resulted in Middle Ages to emergence of a Galmeiflora and heavy metal lawn.

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.
