Abstract : This paper gives data on model tests (scale 1:100) in weak rock (sand) and hard rock (granite) made in Norway and Sweden. Scale depths up to 1 m . kg-1/3 and loading densities up to 100 kg/m3 were tested. For higher loading densities the test in sand and granite gave conclusive results eg mass rather than strength is relevant for debris velocities. Scaled maximum velocity if given as a function of scaled depth. From this maximum velocity debris range can be calculated. Variation of L/D ratios for the charge had minor influence on maximum velocity within investigated range.
