ABSTRACT:
A method and machine for removing blockage and silt from abandoned auger holes preparatory to mining a portion of the remaining ore or preparatory to the placement of charges in said holes. Initially, the highwall is faced up by removing blockage proximate and external to the auger hole as with conventional earth moving equipment. The blockage from within the mouth of the auger hole is removed to expose blockage deposited within the auger hole at locations spaced from the auger hole mouth. Blockage at locations spaced from the auger hole mouth is removed by a apparatus which collapses to penetrate the blockage and is deployed to engage the blockage such that as the machine is withdrawn from the auger hole, the blockage is removed therewith. A device is provided for completing the auger hole cleaning operation by entraining silt or other contaminates in a stream of water and collecting the silt laden water which is transported and discharged at a remote location.
