Automated forecast of pre-outburst coal seam condition in the process of it's working out
In the work criterion of coal seam outburst danger in the process of mining works at the final stage of outburst dangerous situation formation under mining and gas stress action is determined. The criterion is expressed through initial parameters which characterize stressed condition of gas-coal massif, and through the secondary ones which are received with the help of non-destructive control methods: spectral-acoustic and gas-analytical. The work is done with support of RFFI-Kuzbass, grant No. 07-05-96015-R_Ural_a.
