Determining for an output capacity of dimension stone exploitation from the computer simulations to generate the fracture network in 3D: case study in some dimensional stone quarries in Vietnam

Abstract

In dimension stone quarry exploitations such as the marblequarry, a literature review of the existing numerical modelling techniqueshas been carried out. According to Distinct Element Method,discontinuities have been treated as boundary conditions between blocksand, consequently, an accurate knowledge of joint distribution andorientation was required. The result of analyzing data and simulating in thefracture rock environment, which is applied to a mining condition of thedimensional stone quarries. The research we introduce in the outputcapacity of the dimension stone quarry from the computer simulations togenerate the fracture network in 3D with an aim of evaluating the size ofthe blocks. The results of numerical models have been used to optimizesome of the technical parameters for dimensional stone extraction andensuring stable bench in the mining operation.
