摘　　要：板裂化破坏是深部硬岩巷道或硐室典型的破坏形式,严重制约了深部矿产资源的安全高效开发与利用.板裂化破坏诱发因素、发生机制以及控制对策研究已成为岩石力学领域的前沿和热点问题.本文以深部硬岩所处的复杂赋存环境与开采条件为出发点,从开采因素(工程结构尺寸和开挖速率)、环境因素(地质构造和应力环境)和锚固控制3个方面,系统梳理和总结了板裂化破坏在室内试验以及数值模拟方面的研究现状与发展历程.在此基础上,凝练了目前深部硬岩板裂化破坏试验模拟研究中存在的关键科学问题以及关键技术难题.为了保障深井矿山安全高效开采,亟需对深部复杂开采条件下硬岩板裂化破坏机制以及灾害防控开展更为深入和系统的研究,以期为深地矿产资源可持续开发利用提供理论与技术支撑.Slabbing or spalling is the typical failure mode in hard rock tunnels or cavities at great depth, which seriously restricts the safe and efficient development and utilization of deep mineral resources. It is acknowledged that inducing factors, mechanism and controlling strategies of slabbing failure has been recognized as the frontier issue and hot point in the field of rock mechanics. Based on the complex occurrence environment and mining conditions in deep hard rock, the research status and development history of slabbing failure from the perspectives of mining factor(engineering structure size and excavation rate), environmental factor(geological structure and stress environment) and anchoring control by means of laboratory testing and numerical modelling were systematically summarized. On this basis, the key scientific problems and technical challenges in experimental and simulation research regarding slabbing were proposed. In order to ensure the safe and efficient construction and operation, it is urgent to carry out in-depth and systematic research on the mechanism and control strategies of slabbing failure under complex mining conditions in deep hard rock mines, so as to provide theoretical and technical support for sustainable development and utilization of deep mineral resources.
