A mining simulator is a type of simulation used for entertainment as well as in training purposes for mining companies. These simulators replicate elements of real-world mining operations on surrounding screens displaying three-dimensional imagery , motion platforms , and scale models of typical and atypical mining environments and machinery.
Mining saw a particular resurgence as a military tactic during the First World War, when army engineers attempted to break the stalemate of trench warfare by tunneling under no man's land and laying large quantities of explosives beneath the enemy's trenches. As in siege warfare, tunnel warfare was possible due to the static nature of the fighting.

There are two principal phases of underground mining: development mining and production mining. Development mining is composed of excavation almost entirely in (non-valuable) waste rock in order to gain access to the orebody. There are six steps in development mining: remove previously blasted material (muck out round), scaling (removing any unstable slabs of rock hanging from the roof and ...
Tunnel formerly used for coal mining in New Taipei, Taiwan. The use of tunnels for mining is called drift mining. Drift mining can help find coal, goal, iron, and other minerals, just like normal mining. Sub-surface mining consists of digging tunnels or shafts into the earth to reach buried ore deposits.
Drilling jumbos are usually used in underground mining, if mining is done by drilling and blasting. They are also used in tunnelling, if rock hardness prevents use of tunnelling machines. It is considered as a powerful tool to facilitate labor-intensive process for mineral extraction.
The 1st Australian Tunnelling Company was one of the tunnelling companies of the Royal Australian Engineers during World War I.The tunnelling units were occupied in offensive and defensive mining involving the placing and maintaining of mines under enemy lines, as well as other underground work such as the construction of deep dugouts for troop accommodation, the digging of subways, saps ...
Example of a mine gallery with timber roof support. In siege warfare, tunnelling is a long-held tactic for breaching and breaking enemy defences.The Greek historian Polybius, in his Histories, described accounts of mining during Philip V of Macedon's siege of the town of Prinassos; there is also a graphic account of mining and counter-mining at the Roman siege of Ambracia.
