Abstract:
Although the significance of the technical aspects of the mining industry can not be ignored, narrow focus only on technical issues is no longer enough to guarantee economic success, even in the richest ore bodies.On this way results of the economic analysis of particular technological stages of exploitation are an important parameter of productivity and efficiency of the whole exploitation process. This paper presents a model of the economic evaluation of different variants of drilling and blasting, and analyzing the results obtained with the consideration of all the cost of drilling and blasting operation defined in the process of specific grain size production. This is followed by the selection of technically and economically optimal variant of this technological operations in the mineral raw materials exploitation.
