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

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.

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
