Highwall Mining Equipment 1980 A cutting model is developed based on the work of Evans and Mellor; in particular, Evans' equations are modified to treat the three-dimensional, in situ case for drag bits on a circular augerhead.
The highwall mining equipment dictates the hole width which varies from 2.7 to 3.6 m (9 to 12 ft). In situ vertical stress depends on the overlying rock density and overburden depth. Vertical stress gradient is typically 0.025 MPa/m (1.1 psi/ft). Overburden depth may be taken as ...

03-07-2015· Highwall mining is very similar to auger mining in its concept, where the entry into the coal seam in made at the highwall of the ultimate pit limit. The difference lies in the use of a more sophisticated machine, known as a highwall miner. The highwall miner shares some common elements with a continuous mining machine.
Highwall stability is essential for open-cut mining.In these particular projects, otherwise known as open-pit mining, employs a technique in which rock and minerals are extracted from a borrow pit, or sandbox.For long-term highwall performance, the substance properties that makeup mining sites—or more specifically, the rocks and minerals found within the borrow—should be carefully examined ...
