A Review of Highwall Mining Experience and Practice
The highwall mining method originated in the USA in the 1940s. The aim of the method was to recover coal from a surface mine that has reached its economic limit. The coal is accessed at the base of the highwall from where a series of parallel entries are driven into the coal seam. Since 1991, highwall mining has been commercially used in Australia in approximately 40 pits at 17 …
