Abstract: The Tashtagolsky iron ore deposit was furnished with the GITS seismic monitoring system developed by VNIMI JSC early in 2022. The system includes underground seismic pavilions equipped with three-component DRC-11 accelerometer sensors, as well as the day-light surface part with a recording unit and a computer for signal processing. Control of the system, adjustment of the registration parameters and data processing is made via remote Internet connection. At present the system is mainly used to locate focal point of seismic events and to plot zones of seismic activity and rock-bump hazards. Seismic events are recorded in the computer memory when the vibration amplitude exceeds the threshold levels on several sensors. The recorded events are processed by the operator, their coordinates and energy are calculated and noise is removed. As the result, a registry is generated that includes the exact time, coordinates and energy of each recorded event. Data from such registries makes it possible to plot changes in the main parameters of seismic activity, identify spatial zones of seismic events concentration and their location in relation to areas of mining operations. The rock-bump hazards is controlled based on observations of formation and migration of the seismic activity zones. Сontinuous readings of each seismic sensor during the background vibrations, which reflect the state of the rock mass hic et nunc, could be a further development of seismic monitoring systems in deep ore and mineral mines in addition to the existing monitoring methods. The authors propose a method to process long continuous records (staring from one day or longer) of the seismic noise, during which it is not the signal itself that is analyzed, but its spectral characteristics, and the objective is to detect changes in the spectral composition just before a strong seismic event is registered.
