Abstract: The paper reviews the main causes and factors affecting the rock mass movement processes. Based on instrumental surveys performed by specialized organizations it was established that the rock mass movement develops slowly and evenly without sinkholes and large cracks on the ground surface. The protection measures for buildings and facilities can be divided into two types: mine protection measures and structural measures. The main facilities at the Talnakh deposits that are subject to protection are generally located within the service sites for auxiliary ventilation, rock and material shafts. These facilities are used mainly for industrial purposes. Industrial buildings include, first of all, surface shaft facilities (buildings and the winding towers), hoist engine buildings, stowage facilities, large ventilation and compressor units, mechanical repair shops, electrical substations, administrative and amenity buildings, etc. Currently, the main protection measure for the above mentioned facilities is backfilling of the mined-out space with solidifying compounds, which drastically reduces the amount of deformations in the rock mass and on the ground surface and, as many years of experience have shown, ensures uninterrupted operation of most of the facilities within the mine impact zone without applying additional mining and structural protection measures.
Keywords: mining, parameters of the rock mass displacement, mine impact zone, backfilling of the mined-out space with solidifying compounds, protection measures for facilities and natural objects, protection of undermined facilities
