The broken ore slides down the funnel into the raise which serves as a chute, the ore being drawn off through gates into cars on the haulage level. This is a cheap method of mining, but it is dangerous especially if pieces of the wall tend to break off and the excavation is large. A series of holes may be mined until they intersect.

Block caving is essentially the underground version of open-pit mining. It’s the only underground mining method that can reach similar production rates to surface mining operations, up to over 100,000 tonnes per day. The method involves undermining an ore body, then allowing it to collapse under its own weight.

There are five basic types of surfacemining, including open-pitmining, stripmining, dredging, mountaintop removal, and high wallmining. All of thesemethodsremove the waste material or the overburden, which is above the desired resource. Often, surfaceminingis preferred overunderground mining, or subsurfacemining, for numerous reasons.

Underground mining methods adapt to the conditions and form of the rock, as well as to the dimensions, strength and stability of the mineralized body. Excavation and the construction of an important range of infrastructure (workplaces, power supply, transport, drainage and pumping, maintenance) are required in order to access the ore and obtain the metal.

PDF version. There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
