Present Situation and Consideration of Rock Burst Hazard

Abstract:

Article Preview

Rockburst is a sudden disaster that endangers greatly the security of operators and facilities in the production.The problem of rockburst is the most important issues in the underground space. This paper describes the present situation of the disaster at home and abroad ,which includes the conception,classification, intensity classification, mechanism, forecasting, and prenvention. Based on these analysis, This paper summarizes the following questions:Conception and intensity classification of rockburst has not level , its major and minor influencing factors has not compartmentalized; without taking full consideration in the influence of rock mass structure and dynamic action in comprehensive prediction, and there are fewer considerations of it in practical project; Attribute weights of all the factors are always subjectivity, it can not give the mathematical explanation; Study on rockburst mechanism are not enough, It can not exactly prodict when and where occur,can not raise the perfect time to prenvent the disasters.At the end of this paper, it is pointed out that it is the emphasis topic which comprehensive prediction with computer.
