EXPERIENCE THROUGHOUT THE WORLD WITH THE CSIR "DOORSTOPPER" ROCK STRESS MEASURING EQUIPMENT

THE CSIR "DOORSTOPPER" ROCK STRESS MEASURING EQUIPMENT WAS DEVELOPED FIVE YEARS AGO AND DURING THE PAST THREE YEARS HAS BEEN COMMERCIALLY AVAILABLE. "DOORSTOPPERS" HAVE, AS A RESULT, BEEN USED IN AUSTRALIA, CANADA, GHANA, GERMANY, ITALY, SPAIN, SWEDEN, NORWAY, BRITAIN, RHODESIA, SOUTH AFRICA, UNITED STATES AND ZAMBIA AND PROBABLY IN OTHER COUNTRIES AS WELL. AN INSTRUMENT USING THE SAME PRINCIPLE HAS IN FACT, ALSO BEEN USED IN POLAND. AN ASSESSMENT IS MADE OF THE PUBLISHED RESULTS OBTAINED WITH "DOORSTOPPERS" THROUGHOUT THE WORLD IN MANY TYPES OF ROCK AND UNDER VARIED FIELD CONDITIONS. THE VERSATILITY AND THE POTENTIAL OF THE "DOORSTOPPER" EQUIPMENT IS EVIDENT FROM THIS ASSESSMENT. /AUTHOR/
