Abstract

The invention relates to mining and can be used for diagnostics of state of rock massif, with that for determination of outburst danger of coal seams included, prediction of rock bursts at implementation of mining operations in openings and stopes. One determines artificial and natural acoustic vibrations that come to existence in rock massif at affecting it with mechanisms, with determination of rate, phase, amplitude parameters of acoustic vibrations with following integrated analysis of those, with comparison to critical values, and determination of probability of gas-dynamical manifestation is determined from ratio. The method is realized with use of apparatuses to which block of primary processing is included, block of decoders, additional group of filters and block of analyzer. The method makes it possible to increase level of probability at advanced identification of possibility of development of sudden outburst of coal, rock and gas in underground workings with purpose of more reliable evaluation of stressed state of rock massif round working in real time and increase of work safety for underground personal, with that of coal mines included.
