Block caving: A new mining method arises |
Block caving is an underground hard rock mining method that involves undermining an ore body, allowing it to progressively collapse under its own weight. It is the underground version of open pit mining. In block caving, a large section of rock is undercut, creating an artificial cavern that fills with its own rubble as it collapses. This broken ore falls into a preconstructed series of ...
Underground Mining Methods
Underground Mining Methods Teacher Information drilling of the now higher roof continues. The roof is blasted till it is so high that it cannot be reached by a jumbo. Then a jumbo working in a higher elevation drift is used to intersect the stope. After blasting, the ore falls down to the lower drift where LHDs can drive in to load the muck and dump it at an ore pass. Drilling and blasting ...

5 Types Of Underground Mining Method You Should Know 2021
Strip mining is the most destructive underground mining method, as it leaves behind large open pits and destroys habitats. Strip mines are often referred to as "deserts on land" due to how much land they take up and how lifeless they are when all vegetation has been removed for processing. The process starts with removing earth from an area in layers until you reach the desired ore beneath ...

The Four Main Methods of Mining
· Underground mining; Underground mining is a method of mining that extracts ore from underneath the earth's surface. The entry from the earth's surface to the underground mine may be created via a horizontal or vertical tunnel (also known as adit, shaft, and decline). Underground mining is used when the ore body is too deep to be profitably mined by open pit, or when the quality of the ore ...
