IPC: E21D9/10
Filed: 1985-03-12
Abstract: A hole is drilled in a front (9) of hard material, such as rock, by fragmenting the hard material with impact hammers (13a) along a plurality of spaced-apart paths extending in parallel planes (P1, P2,P3), each of which extends in a plane different from the planes in which the adjacent paths extend. The hammers (13a) are mounted in parallel, spaced-apart relationship on a support (15), each hammer having a head (17) spaced from the support (15) by a different distance from the adjacent hammer heads. The hammers (13a) are driven towards the front (9) by a motorized vehicle (5), and are simultaneously reciprocated in a plane parallel to the front (9) The fragmentation by impact along the paths causes simultaneous fragmentation by shear between the paths.
