Description:

The baseline intact rock strength of a rock mass can be determined by a relatively simple test known as the and estimation by so-called ‘simple means’ test. Estimation by ‘simple means’ denotes estimating the intact rock strength by hammer blows,crumbling by hand, etc. Many different people to avoid observer bias have done hundreds of assessments of intact rock strength by different means on the same rock masses. The results show that in many cases an estimation of intact rock strength by ‘simple means’ is more representative for establishing the intact rock strength of a rock mass than establishing the intact rock strength by more elaborate testing.
