Large-scale, dynamic rock mass failure mechanisms in mines

过去几年，加拿大一些矿山发生了大型采矿诱发地震事件，这对深部采矿作业构成了重大危害。 提出了一个研究项目，以调查大规模的岩体破坏过程中发现的深部矿山，包括支柱故障，堤坝故障，断层滑动事件和剪切破裂事件的地震学性质。 本研究项目的主要目标是描述与不同破坏过程相关的地震活动性。 最后，这一特性将导致更早地发现故障过程，从而有更多的机会管理与大型采矿引起的地震事件有关的风险。

Large mining-induced seismic events represent significant hazards to deep mining operations, occurring in a number of Canadian mines in the last few years. A research project is proposed to investigate the seismological nature of large-scale rock mass failure processes found in deep mines, include pillar failures, dyke failures, fault-slip events and shear-rupture events. The main objective of this research project is to characterize the seismicity associated with the different failure processes. Ultimately, this characterization will lead to earlier detection of failure processes giving greater opportunities to manage the risks associated with large mining-induced seismic events.
