Abstract
A surface instability detection apparatus for investigating axial splitting and spalling phenomena in rocks and rock-like materials is described. The apparatus simulates the conditions under which these phenomena occur and allows one to accurately measure them. Experimental results from tests on Berea sandstone are presented where the successive formation of spalling fractures was monitored with an acoustic emission system and the location of the seismic events was mapped. The test results show the potential for benchmark tests in determining the spalling tendency and characteristics of different rocks.
