Abstract

The functioning period of the communication tunnels` system should be appraised by the economic indicators, which takes into account the value changing of the probable loss in time of their exploitation. On the first stage, the basic data for the collector tunnel projecting is determined: its purpose, its key parameters, as well as the directive construction time and the service lifes of the underground facility. On the second stage, the choice of the construction method of the communication tunnel is realized on the basis of the evaluation of the mining and geological and hydrogeological conditions, as well as the factor cost on the construction. After the choice of the construction method of the collector (open cast or underground), the existing or probable path irregularities are determined. Then, the engineering and technological schemes of mining and construction works` production are chosen. The costs, implementation times and expected project efficiency are determined with checking on the indicated above restrictions of the economic-mathematical model and choosing the most effective alternative.
