Rockburst Dangerous Area Dividing in Guo-Tun Deep Mine

With the development of deep coal resources, rockburst, as a kind of typical underground dynamic disaster, always threats the production safety. Before the mining design, it is very necessary to forecast the possibility of the rockburst. This paper takes the Guo-tun coal mine for the object, considering the specific geological conditions, to predict the possible dangerous area where rockburst would happen. Through the comprehensive research and analysis, the paper would divide the 1312 working face into some probalble dangerous zones, namely strong shock hazard zones and medium dangerous impact zones, during gateway driving and stopping.
