长期以来岩爆一直是影响地下工程稳定性的重要因素，尤其是在深埋高应力条件下。本文对近期岩爆现场研究的进展进行了全面回顾，涵盖了现场案例分析、监测方法、预警系统和风险评估。首先，总结了基于现场勘察的岩爆概念和分类。通过分析己发表的岩爆案例和现场调查结果，详细评估和讨论了结构面(在不同空间分布组合下)、地应力(尤其是主应力的大小和方向)、动力扰动和开挖轮廓对岩爆的影响。接下来，概述了常用的现场监测技术，并描述了它们各自的技术特点。特别强调了微震(MS)监测技术的有效性及其在岩爆动态预警机制中的潜在应用。在此基础上，验证了考虑现场变量评估岩爆倾向的可行性，包括相关指标的选择和定量评价。最后，对本文进行了全面总结，并提出了未来研究的目标。
A review of rockburst:Insights from engineering sites to theoretical investigations
Rockburst has perennially posed a formidable challenge to the stability of underground engineering works,particularly under conditions of deep-seated high stress.This paper provides a comprehensive review of recent advancements in on-site research related to rockburst occurrences,covering on-site case analyses,monitoring methodologies,early warning systems,and risk(proneness)evaluation.Initially,the concepts and classifications of rockburst based on on-site understanding were summarized.The influences of structural planes(in various spatial distribution combinations),in-situ stress(particularly magnitude and direction of the principal stress),dynamic disturbances,and excavation profiles on rockburst were thoroughly assessed and discussed through the analysis of published rockburst cases and on-site survey results.Subsequently,a compendium of commonly employed on-site monitoring techniques was outlined,delineating their respective technical attributes.Particular emphasis is accorded to the efficacy of microseismic monitoring technology and its prospective utility in facilitating dynamic rockburst early warning mechanisms.Building upon this foundation,the feasibility of assessing rockburst propensity while considering on-site variables is verified,encompassing the selection and quantitative evaluation of pertinent indicators.Ultimately,a comprehensive synthesis of the paper is presented,alongside the articulation of prospective research goals for the future.
