Early identification of fault zones during excavation and construction of underground mine workings is of key importance in terms of safety of mining operations. The importance of predicting striking of dynamic impact zones by a mining route lies in the fact that the zones under consideration are often associated with a set of complicating factors: increased water cut, gas release, as well as gas-dynamic phenomena. Understanding their linear dimensions is an important parameter for determining technical measures aimed at advanced degassing, drying and unloading of rock mass. Studying and predicting zones of dynamic influence of faults is most critical in underground development of such unique deposits as the Internatsionalnaya Pipe. Detection and study of subvertical zones of discontinuity (zones of crushing) in rocks, and assessment of the elastic moduli of rock mass was carried out by seismic methods based on recording signals of reflected waves at distances from 5 to 200 m. The use of the Mikon-GEO hardware and software system made it possible to determine natural and manmade anomalies in rock mass. Additionally, to check this method, a set of tests was carried out to detect already proven manmade zones of strength loss in rock mass—cage and skip shafts. As a result, it is found that this method can be used to reliably detect the stress loss zones with a thickness of more than one meter. Detection of lower-rank faults using the applied methodology is currently difficult and requires additional research and development.
