Different techniques are used in mining. They are divided into two different excavation types. These are underground and surface mining.
Surface mining is the most common. The bulk of minerals, diamond and silver included are gotten through surface mining. Surface mining is carried out by getting rid of all surface vegetation and rock layers. This is done to reach the ore deposits.
On the contrary, the digging of shafts and tunnels with the aim of reaching the ore is what is involved in underground mining, also referred to as subsurface mining.
The mining of minerals requires the use of heavy machinery. As far as land extraction is concerned, bulldozers, explosives, trucks and drills are essential. Miners and the minerals are transported using trams while lifts carry them in and out of the mines. Huge trucks, shovels and cranes are used for purposes of moving large amounts of ore in surface mining. Machinery to be found in processing plants include roasters, crushers, mils and reactors. They help in the extraction of metals, minerals as well as other vital materials from ores.
It was the Romans who made great development in the history of mining. They were the first ones to use large scale quarrying methods such as the use of volumes of water to operate simple machinery, remove debris, and so forth. This has come to be known as hydraulic mining or hydraulicking. This is a form of mining that uses high-pressured jolts of water to move rocks and other debris.
In the 1300s, the demand for metal to swords, armors, and other weapons increased dramatically. More minerals such as iron and silver were extensively quarried. The demand to produce coins likewise increased to the point of causing a shortage of silver. During this period, iron became an indispensable component in building constructions; machineries and other mining equipment became prevalent.
From open-pit mining, water mills and black powder have evolved into bulldozers, explosives, trucks, and so on. Other technological innovations such as green light laser used in mining as saw guides and machine alignment help miners quarry lands.
From pre-historic tools, large machineries are now used to effectively and quickly excavate lands. These are also used to break down and remove rocks, even mountains. Custom engineered equipment now helps in the extraction of various precious minerals and other bedded materials such as gypsum and salt.
Today, there are currently five categories of mining: coal, metal ore, non-metallic mineral mining, oil, and gas extraction. Oil and gas extraction remains to be one of the biggest industries in the world today.
