ABSTRACT:
A method of reclaiming a highwall or sharp cliff like exposure mining site. The method includes the steps of placing a first series of directional charges at preselected locations in each of the auger, longwall or deep mine entry holes proximate the opening of the hole on the face of the highwall. Directional charges are positioned on the floor of the holes and pointed upward, obviating the need to drill charge placement holes. Such solid placement maximizes the explosive impact on the overburden above the charges thereby creating rubble from the overburden and tearing out sections of the in-situ material separating the holes. In one embodiment, a further series of charges is detonated at a preselected interval in time and depth from the detonation of the first series of directional charges to provide a synergistic explosive effect to accomplish the reclamation process.
