Spectral-acoustic method for outburst danger prediction considering in-situ gas pressure
FRC CCC SB RAS. Prosp. Leningradskey, 10, Kemerovo city, 650065, Russian Federation
The option of spectral-acoustic method for coal seam outburst danger prediction based on the influence of outburst danger basic factors on the amplitude-frequency characteristic of acoustic vibration median formed when breaking the rock massif by the operating mining equipment is justified. Basic outburst danger factors are: rock pressure, in-situ gas pressure, coal strength.
