RDi : A new method for evaluating of rock mass drillability
, 2007 In open pit mining drilling, like the other stages of mining, has a close relationship with the rock mass. The drilling process and its results are affected by various parameters of the rock material and rock mass. The effects of rock materials have been

Prediction of strength and deformability of an interlocked blocky rock mass using UDEC
Journal of Rock Mechanics and Geotechnical Engineering, 2017 The accurate prediction of strength and deformability characteristics of rock mass is a challenging issue. In practice, properties of a rock mass are often estimated from available empirical relationships based on the uniaxial compressive strength (UCS).

Modelling rock slope behaviour and evolution with reference to Northern Spain and Southern Jordan [PDF]
, 2004 The geomorphological behaviour of steep jointed rock slopes has been studied using distinct element computer models. In order to model steep slopes effectively, methodologies need to be combined from the studies of environmental modellers ...
