Study Of Geometrical Properties Of Blocks In A Jointed Rock Mass Using Statistical Geometry

Knowledge of geometrical properties of blocks in a hard jointed rock among other things is of considerable importance for prediction of rock mass behavior and for its exploitation. This paper presents a new approach to obtain the information about percentage of blocks with desirable geometrical properties in a jointed rock mass extending through a large region of interest. A model of a rock mass separated by finite number of systems of parallel plane discontinuities which form discrete blocks is discussed. A computational procedure has been derived to analyze the volume and shape distribution of blocks in the rock mass.
