Mathematical justification on the choice of explosive material to rupture strong rocks of complex structure
Journal Title: Metallurgical and Mining Industry - Year 2017, Vol 9, Issue 5
Abstract
This work outlines the relevance, the purpose, the problem, the methodology and the results of research on explosive materials applied for rupture of strong rocks. The purpose of this paper is to justify mathematically the choice of the type of explosive materials (hereinafter referred to as EM) with taking into account many criteria for this kind of practice. In the course of the current research, the selection of the alternative variants of the EM type for the rupture of strong rocks of a complex structure has been carried out. Our choice and the justification are based on many criteria (technological, economical, social and other indicators). The priorities for a systematic approach to the problem solution have been defined, namely: not only the benefits have been taken into account, but also the costs associated with the use of an explosive material. Factors characterizing costs when using charges from different types of EM have also been considered. The solution of the problem has been carried out with the use of the hierarchy analysis method, which makes it possible to incorporate both quantitave, and qualitative criteria as well as to make judgement as to their significance for the choice of EM type, and also to check the consistency of expert opinions that are regarded in solving the problem. Based on the results of the problem solution, a vector of priorities has been obtained for each of the hierarchs, which allows us to justify the choice of the type of EM.
