In Russia, as well as in many countries, there is a tendency of conditions complication for the minerals development. Almost all mining enterprises are classified as hazardous production facilities. Russia occupies one of the leading places in the world in the mining industry, but, unfortunately, accidents occur on its territory, resulting in injuries and death of workers. Accidents at a mining enterprise can occur for various reasons, including changes in the geomechanical and geodynamic state of the rock mass under developing, where dynamic manifestations of rock pressure can be initiated by mining operations or rock impacts, as a result of which people may suffer.
The first part of this work provides an analysis and comparison of sources on accidents in the mining in-dustry in Russia for 2017-2022, showing that accidents at a mining enterprise can occur for various reasons. This problem is present in our country, people are dying and being injured and this trend continues. Statistics on accidents that occurred as a result of dynamic manifestations in the mountain range are considered in more detail.
The second part of the work describes the development and installation of measuring instruments for the creation of a geodynamic polygon for complex geomechanical monitoring of impact hazard and technogenic seismicity in the Dalnegorsky ore region. In particular, it shows the design with use of the "AntennaCalc" program and a volumetric digital model of the geophone network field and the installation of an automated mountain pressure system "Prognoz-ADS" at the Southern field, which is dangerous for mountain im-pacts.
