Abstract
Cutting of artificially frozen gravel and ice was performed under laboratory conditions at pressures ranging from 3000 to 15000 psi (20.7 to 103.5 MPa) and flow rates below 4 gpm (0.24 L/s). During the second stage of this preliminary study additional cutting and "drilling" were conducted in the permafrost tunnel at Fox, at pressures ranging from 2000 to 4400 psi (13.8 to 30.4 MPa) and flow rate up to 40 gpm (2.4 L/s). The erodability of the material (energy required to remove a unit volume of material) was calculated and used as a basis for finding the optimum conditions for frozen gravel disintegration. Recommendations for further studies are also included.
