Abstract
Underground drift construction in underground mines affects the disturbance of the balance that prevails in the primary rock mass. In such an environment, there is a redistribution of stress in the rock medium and the formation of a secondary field stress around the underground drift. Importance of the supporting underground drifts is reflected in the fact that only by installing an optimal support structure, safe conditions can be ensured for the continuation of work. Total installation costs and required installation time can be highly rationalized by choosing the right type of support. Comparison and ranking of anchors in this paper was carried out according to different criteria: stability of the drift, required installation time and costs of support installing. In order to evaluate the precision of the obtained results and to ascertain whether the prescribed support structures imparted requisite safety to the subterranean enclosure, stability analysis was created utilizing Rocscience Phase software. Selection of the optimal type of anchor according to the above criteria was carried out using the Analytic Hierarchy Process (AHP) method. The analysis and evaluation of the obtained results according to the specified criteria was performed using the Expert choice software.
