Abstract
A machine for mining hard material in-situ between adjacent auger holes is disclosed which is suitable for being drivingly connected to a conventional mining apparatus, particularly an auger mining apparatus. The mining machine includes cutting apparatus for mechanically contacting and dislocating hard material in-situ between adjacent auger holes. A power operated system is drivingly connected to the cutting apparatus for generating a cutting motion during the in-cutting operation. A guiding system is provided for maintaining the cutting apparatus in mechanical contact with hard material in-situ between the adjacent auger holes. In one embodiment of the invention a collection bin collects the dislocated material which is transported from the position at which the material is mined to a remote location for deposit.
