ESTIMATION OF ROCKBURST HAZARD FACTORS OF THE NIKOLAEV DEPOSIT WITH THE USE OF 3D MODELLING RESULTS OF SEISMOACOUSTIC MONITORING

Abstract

The study of the properties and state of natural and
technical systems requires interdisciplinary research
involving the processing and joint analysis of various
data, as well as working with instrumental observation networks, measurement systems, etc. This requires the development of efficient algorithms, technologies, and high-performance computer systems to work with heterogeneous volumes of scientific data, which should provide a comprehensive solution to the problems of collecting, integrating and processing large amounts of information. In this regard, it is very relevant to formulate research work aimed at developing scientific and methodological foundations and technical means for assessing and monitoring dangerous geomechanical
processes to reduce the risk of man-made disasters in
the development of mineral deposits. In order to establish the main factors that determine the manifestations of rock bump danger and technogenic seismicity in the deep horizons of the Nikolaevsky field, studies were conducted which consist in comparing the results of seismic and acoustic monitoring with the geological features of the Nikolaevsky field, with the use of 3D models. This method differs from the known ones because it uses direct measurements of the studied characteristics. Detailed maps of isohypse and isopachyte contours of the four main geological rocks, which reflect the modern deep architecture of the main horizons of the Nikolaevsky field and have different physical and mechanical characteristics, were constructed for the research. Based on the work carried out, we can conclude that the main factor determining the rock bump danger of the deep horizons of the Nikolaevsky field is the timing of mining operations to tectonic structures.
