Discover a method for achieving great depths of cone testing at high speeds with Gregg’s RaptorCPT system. Learn about a recent project where we pushed a 172 m (564 ft) CPT sounding through mine tailings at Pinto Valley mine in Arizona utilizing both a surface push CPT plus the Raptor-CPT wireline system with a drill rig. Pore pressure and seismic measurements and interpretations are addressed. The full paper is part of the Tailings & Mine Waste 2023 conference proceedings.
