Open Cut and Underground Mining iMINCO
20191122&ensp·&enspWhat are the differences between opencut and underground mining? Open Cut Mining. There are many differences between open cut and underground mining. When minerals and deposits are found close to the surface and spread across a large distance, the best way to mine is to use the open cut mining method.

Digging deeper: Mining methods explained Anglo American
Underground mining is practical when: The ore body is too deep to mine profitably by open pit. The grades or quality of the orebody are high enough to cover costs. Underground mining has a lower ground footprint than open pit mining. The underground mining methods we use include room and pillar, narrow vein stoping and largescale mechanised
shaft mine: types of mines Students Britannica Kids
The diagram depicts a cross section of three different kinds of mines, along with structural elements of the underground shaft and slope mines. The shaft mine has compartments for a skip hoist, elevators called cages, and service facilities such as ventilation ducts. In a slope mine, the miners also work at different levels, and the ore is sent to the surface in bucket hoists.

Mining Underground mining Britannica
Mining Mining Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the

Underground Mine Gas Monitoring Unidata
This appliion note details how monitoring in a mine may be achieved. Gas buildup in underground mines is very dangerous as it can cause explosions which can result in injury or loss of life for mine workers. Such explosions are also costly as mine tunnels, mine shafts and expensive mining equipment can be destroyed.
