Ground support is widely implemented to mitigate dynamic rock failures in underground mines. This paper investigated the ground support requirements in burst-prone mines to mitigate the catastrophic dynamic rock failures of rock and/or coal bursts. First, the ground support principles and considerations in burst-prone conditions are identified. The objective of a ground support system is to increase the capacity to accommodate rock fracturing in a rockburst and, in turn, to minimize the kinetic energy of the ejected material. The support capacities of various yielding rockbolts and integrated support systems are then investigated using the test results in the laboratory. Apart from the energy absorption and yielding deformation capacity, the initial stiffness and energy absorption rate are also critical factors when applying yielding rockbolts in practice. Adding rope lacing and mesh strap to surface support elements can substantially enhance the support performance of the system. In practice, semi-analytical and empirical approaches are often used to determine the ground support elements in burst-prone areas. Semi-analytical methods first evaluate the support demand in burst risk zones and then select support elements according to their laboratory test results. Alternatively, empirical methods determine the ground support elements according to the locally established empirical rating scheme, which usually ranks the support capacities of various support systems based on ground support conditions and damage conditions. The outcomes of this study can provide insights into ground support strategies and assist the mining industry to develop effective coal burst control technologies.

广泛实施地面支撑以减轻地下矿山的动态岩石破坏。本文研究了易爆矿山的地面支撑要求，以减轻岩石和/或煤爆的灾难性动态岩石破坏。首先，确定了易爆条件下的地面支持原则和考虑因素。地面支撑系统的目的是增加在岩爆中适应岩石破裂的能力，进而最大限度地减少喷射材料的动能。然后使用实验室的测试结果研究各种屈服锚杆和集成支撑系统的支撑能力。除了能量吸收和屈服变形能力，在实际应用屈服锚杆时，初始刚度和能量吸收率也是关键因素。在表面支撑元件上添加绳索系带和网带可以显着增强系统的支撑性能。在实践中，通常使用半分析和经验方法来确定易爆地区的地面支撑元素。半解析方法首先评估爆破风险区域的支撑需求，然后根据实验室测试结果选择支撑元件。或者，经验方法根据当地建立的经验评级方案确定地面支撑要素，该方案通常根据地面支撑条件和损坏情况对各种支撑系统的支撑能力进行排名。
