Abstract
In the framework of geo-information model of coal deposit and open pit mine, the author derives analytical expressions for calculating work of rock transportation from face to start point of transport incline, considering road characteristics obtained in the course of geo-information modeling. Alternative calculations of freight turnover and transportation work to overcome gravity and road adhesion are analyzed. The example of calculations for the conditions of a particular open pit coal mine contains comparison of one- and two-flank mining schemes.
