Study On Establishment And Application Of Hazard Evaluation Model For Rock-burst

As the increase of depth and strength of mining, the amount of rockburst mines mounted up.For the safety of those mines, it is very important to adopt measures of prevention and cure according as rockburst hazard. Thereby, hazard evaluation for rockburst is necessary.At the present time, research productions that can be used to guide practice are absent. After analyzing the former research fruits by the numbers and roundly, this paper has analyzed the infection factors of rockburst from geologic and mining conditions, plot the grades of rockburst with reason, and establish the evaluation models according to synthetical index method and theory of quantification successively.To get a simple and applied evaluation method, this paper combined theory of quantification with rockburst hazard evaluation for the first time. As a result , application range of quantification theory has been developed and direct a new way for the hazard evaluation .The result of test indicated that it is feasible to solve this problem with theory of quantification, and it can overcome the shortage of artificial scores, enhance the accuracy and reliability of evaluation for rockburst.Furthermore, rockburst hazard at appointed area of Fuli Mine and Huating Mine had been evaluated by the model. Based on the evaluated result, we can find that prevention and cure measures are available.
