Improvement of the method registration electromagnetic radiation preceded to rock failure

In-situ electromagnetic radiation signals are recorded in the vicinity of faulting zones in enclosing rock mass around roadways in Kirov S. M. coalmine of «SUEK-Kuzbass» using stationary instrumentation, in real time and with data transfer to a surface server. The developed instrumentation made it possible to record variations in the signal amplitude spectrum in the range to 1.0 MHz. The EMR signals associated with dynamic fracturing are specifically pronounced against the general background. Parameters of a signal preceding discontinuity in coal and host rocks are determined. In the zones of softening and fracture of rocks, the number of single high-energy signals jumps, and their amplitudes exceed the overall background level by more than 5 times. It is shown that prior to rock failure, alongside with an increase in the EMR amplitude, a high-frequency component appears in the signal spectrum, which enables more exact detection of failure initiation. Within the package developed for predicting hazardous gas-dynamic events definable using the method of electromagnetic emission, the identification criterion of hazardous zones by the signal amplitude, frequency and their combination is implemented.

Keywords: mine working, electromagnetic emission, recording, stationary instrumentation, rock failure, cracking, crushing, overburden pressure, pressure-induced dynamic events, stressstrain state, electromagnetic radiation, in-situ research.
