地下工程岩爆研究现状综述

Review of rockburst in underground engineering

基于地下工程岩爆研究成果,系统总结了岩爆的定义、类型、烈度分级、影响因素、破坏机理、预测与防治方法。指出目前岩爆研究中存在的主要问题,即岩爆发生的机理不够明确,判据不够充分,工程适用性欠佳,预测手段单一等。提出岩爆综合预测的研究思路,建议将岩爆的预测划分为岩爆倾向性预测、岩爆趋势预测和岩爆现场监测3个阶段。

Based on the research achievements of the rockburst in underground engineering, the definition, types, intensity grades, influencing factors, failure mechanisms, and on-site forecasting and control methods of the rockburst are summarized systematically. The current main problems in the rockburst research including the indeterminacy of the rockburst mechanism, the insufficiency of the criterions, the bad engineering applicability, and the prediction mean singleness are analyzed. A novel thought is given for the rockburst comprehensive prediction. It is suggested that the rockburst prediction should be distributed into three stages： tendentiousness prediction, trend prediction, and field prediction and forecasting.
