LOGGING THE MECHANICAL CHARACTER OF ROCK

TO MAKE THE BEST USE OF ROCK CORE, THE MECHANICAL CHARACTER OF THE ROCK SHOULD BE EVALUATED CONCURRENTLY WITH CONVENTIONAL GEOLOGICAL OBSERVATIONS. THE ADVENT OF SIMPLE TECHNIQUES, SUCH AS THE POINT LOAD 'NUTCRACKER' TEST, MAKES FIELD LOGGING OF MECHANICAL PROPERTIES COMPETITIVE WITH SAMPLING AND TESTING IN THE LABORATORY. /TRRL/
