The article investigates the way of solving the problem of plane deformation mechanics of solids using Mathcad package for evaluation zonal fracturing technology in granite quarries in the process of separation from the array. The Mathcad package has already consisted the program blocks designed to solve plane problem of deformated mechanics of solids, which avoid the need to address the problem by transposition of matrices and finding a root system of algebraic equations. Analysis of the results reveals area of high stress concentration around a bench angle which represents danger zone. With the deepening of the array this concentration decreases rapidly. It is notably that the appearance of zones of tensions are the most dangerous to granitoids. To simulate this process, we propose to combine the classic mathematical apparatus with fracture mechanics criterion for angular Neybera fracture zones on the ledge of a career that will accurately describe the formation of intense angular zones. |
