ABSTRACT

The earliest rockburst activity in the world was recorded at Leipzig Coal Mine, affiliated to Stanford Coal Field in 1738. Since then, the research on rockburst has been continuing without slackening in underground construction. For seeking the possibility of rockburst and its associated intensity, up to now, different methods from different scholars in the world are available. However, it should be noted that the rockburst phenomena are influenced by multiple factors. Unfortunately, the available criteria were derived from single factor or a few factors. In order to refrain from the limitation caused by single factor or by other artificial factors in using fuzzy mathematics for determining the weighting, with reference to commonly used rockburst criteria and classification worldwide, and combining this topic with experiences in Chinese engineering practices, this paper presents a five-factor comprehensive method for rockburst criterion and classification. In addition, some case histories are described for verification.
