The equipment proposed in this application will be used in support of deep mining challenges, in particular to detact and trach mining-induced straining of the rock mass. Issues such as fault slip, strain bursting and rockmass bulking during brittle failure can be better understood if the related strain field is known. Recent developments with distributed strain monitoring technology opens opportunities to fill knowledge gaps as outlined in this proposal.

本申请中提出的设备将用于支持深部采矿挑战，特别是用于探测和追踪岩体的采矿引起的应变。 在脆性破坏过程中的断层滑动、应变破裂和岩体膨胀等问题，如果知道相关的应变场，就可以更好地理解。 分布式应变监测技术的最新发展为填补本提案中概述的知识空白提供了机会。
