<p>Overbreak is a considerable cost factor in underground construction. In literature virtually no information is available relating rock mechanical parameters quantitatively to overbreak. During the construction (drilling, blasting&amp;mucking) of the Soumagne ...

Three methods of in situ deformation modulus (Em) measurements of rock masses have been described, analysed and compared. The plate jacking (PJT) test, where the deformations are measured by extensometers in drill holes, gives generally the best results. A ...
