Abstract
A method of mining that makes use of hydraulic fracturing. The method comprises fracturing an ore body hydraulically by introducing fluid rapidly into a bore or fissure in the ore body such that pressure in the bore or fissure builds up rapidly and it fractures the surrounding ore body. This enables the surrounding ore body to cave into a suitable space such as an undercut from which the ore can then be recovered. The method is particularly useful in block caving as a replacement for explosives.
