As mining progresses to deep grounds, mining-induced rock failure, seismicity and rockburst problems increase significantly. A good mine design strives to avoid rockburst problems in the first place, and achieving this objective requires a good knowledge of the rock mass behaviour, especially in the post-peak region. For example in mine pillar design, the knowledge of rock's post-peak behaviour is essential in the assessment of pillar burst potential.

随着采矿向深部发展，采矿引起的岩石破坏、地震和岩爆问题显著增加。一个好的矿山设计首先要努力避免岩爆问题，实现这一目标需要对岩体行为有很好的了解，特别是在峰后区域。例如，在矿井煤柱设计中，岩石峰后特性的知识对于煤柱爆破潜力的评估至关重要。
