Experimental study of the outburst risk prediction in excavating face
This paper directed toward the problems of the prediction indexes is different，the prediction indexess critical value is different，the prediction effectiveness is not reliability and Four-process-in-tunnelling changes to Three-process-in-tunnelling in the same coal bed。From the research of prediction index in 16121 excavating face in Daping Coal Mine Xinmi Mining Area,we gets the sensitive indexes and its critical value in the mining area,and gives up part of the used prediction indexes that is not sensitive in the mining area.From this research we realize the exploring prediction index of the outburst hazards is not enough in excavating face,and put forward several viewpoints.
prediction index the initial velocity of gas emission (q) the amount of drillings coal powder (S) the amount of gas desorption (Δh2)
