20130247693 | Method for Sampling Jointed Rock Mass - The present disclosure relates to a method for sampling rock mass, especially jointed rock mass. The present disclosure provides a simple and convenient method for sampling jointed rock mass to prevent the rock sample from being disturbed and damaged during sampling and accordingly resulting in opening of the weak structural planes, to therefore obtain rock specimen correctly reflecting the basic physical and mechanical characteristics of rock mass comprising integral fissure network. The method for sampling jointed rock mass of the present disclosure comprises the following steps: Step a: Siting; Step b: Drilling; Step c: Protecting; and Step d: Sampling. The method is suitable for determining the basic mechanical properties of the rock mass and for assessing the stability of caverns in jointed rock mass. | 09-26-2013 |
