Abstract
The invention relates to an equipment for boring large diameter holes into rocks. The equipment comprises a cylindrical core tube (12) having a vertical axis, an upper end (12a) and a lower end (12b), a plurality of hammer (14) provided with percussive bits (14b) for penetrating into the rock, each hammer being secured to the outer face of the core tube close to the lower end thereof so that the bits project beneath the free end (12c) of the tube, pressure fluid means (22) for operating said hammer, pressure fluid feed means for supplying pressure fluid in the vicinity of the bits of said hammer, driving means (16) connected to the upper end (12a) of said core tube for rotating said core tube about the vertical axis thereof and exhaust means (24) connected to said core tube for collecting the pressure fluid supplied in the vicinity of the bits and the rock cuttings transported by said pressure fluid from the bottom of the hole to the ground surface. <IMAGE>
