Abstract
The paper presents an analysis of the method of recording the magnetic component of the Earth’s natural pulse electromagnetic field in an urban environment. This method of recording has already proved itself to be a method that allocates the stressed sections of rock mass at mining and, therefore, the authors consider it effective for allocating active tectonic disturbances and forecasting accidents at underground utilities, which will help reduce the potential environmental hazard of these objects.
Highlights
According to the results of multiyear research aimed at predicting a rock-bump hazard at ore and nonore deposits, it was revealed that the indicator of the modern geodynamic activity of faults is the variability of the Earth’s natural pulse electromagnetic field (ENPEMF) characteristics in space and time compared to the adjacent areas
Comparison of the sampling obtained with the ENPEMF magnetic component (MC) measurement results;
It is worth noting that the complexity associated with allocating low-ranked disturbances, with a high probability, is not substantiated in terms of the method accuracy with respect to the allocation of potential emergency sections on pipelines since, as a rule, in diagrams, such disturbances are presented in the form of a single fluctuation zone, and to implement the most reliable allocation thereof, the existing measurement techniques should be substantially altered
Summary
Small-amplitude movements along faults can result in discontinuity in residential engineering structures, accidents in heat distribution networks and water discharge systems, gas and oil pipelines, as well as in tunnels [7]. According to the results of multiyear research aimed at predicting a rock-bump hazard at ore and nonore deposits, it was revealed that the indicator of the modern geodynamic activity of faults is the variability of the ENPEMF characteristics in space and time compared to the adjacent areas. The team of authors proposed to adapt the method of measuring the ENPEMF MC for the urban environment For this purpose, a number of streets have been selected along which underground utilities are laid and where accidents have been recently registered, namely, pipeline breaks, ground collapses, and associated liquid spills
