ABSTRACT

The design of stationary objects at deep mines is associated with the issue of finding the optimal balance between reducing the transportation distances for personnel, self-propelled equipment, possibility producing of technological processes to mining sites and ensuring long-term operation of mine workings located in the zone of influence of the front of the second workings.

To choose the optimal solution, it is necessary to take into account geomechanically safe functioning of a stationary object near zones with potential stress concentration (tectonically faults, weak rocks and etc.). To avoid negative consequences, the decision must be made on the basis of geotechnical calculations and modeling using specialized software—strength analysis systems.

Two different examples of the use of finite element modeling are described in the article. In the first example, it is possible based on the results of the simulation, to draw conclusions about the effectiveness of measures to ensure the stability of mine workings. Based on the results of the second example, it is possible to draw conclusions about the rationality of locating a capital construction of underground structures at great depths in the rocks with known physical-mechanical characteristics.
