Abstract
The paper presents the results of observations of stress-strain state at the Barentsburg coal deposit by means of the «Angel» equipment with the the purpose of detecting sections prone to manifestation of dynamic forms of rock pressure. The investigated sections of mine field were flooded for a long time, therefore after drainage the original cycles of geophysical measurements have been conducted at all development workings and at production face by applying recording techniques for natural electromagnetic emission, recording of background component of natural electromagnetic field of the Earth, seismoacoustic emission (shock) and seismoacoustic emission (natural), pulsed by points (profiles) along the workings. Parallel with geophysical observations measurements with KDM-1 device were made and visual ob- servations were carried out.
