Method of estimation of rock fracturing
Authors:
Abstract
Usually rocks are fractured, so to judge the deformation of the rock during impact or explosion, it is necessary to be able to determine the wave resistance of fractured rocks.As a first approximation, let us assume that parallel cracks in the rock are combined into systems, in each of which the crack opening d and the distance between them a are constant. Let us assume that the rock is penetrated by three mutually perpendicular systems of cracks and that the cracks are filled with a substance with wave resistance. Let us denote the ratio of crack openness in each system (è = 1. 2, 3).
