Rock stability estimation tasks on anthropogenic soils require both preliminary survey and on-going real-time monitoring providing alerts on possible cave-in threats. Using VLF monitoring data incorporated into software-hardware geodynamical processes automated surveillance system allows to accomplish that task. Authors describe a unique method, based on Earth’s natural pulsed electro-magnetic field (ENPEMF) recording and make conclusions on the efficiency of the solutions ap-plied for hazardous geodynamic processes monitoring on anthropogenic soils. The principle of the method is to distinguish spatial variations of ENPEMF signal against diurnal oscillations and tech-nogenic signals. Correlation between relative signal intensity and stress-strained state of the rocks is experimentally demonstrated.
