Data driven seismic hazard evaluation in Canadian mines

大型地震事件在加拿大深部矿井中经常发生。在安大略省和魁北克省，统计数据显示，每月几乎记录到3次大型地震（震级= +2）。这是一个常见的行业问题，发生在许多矿山。在安大略省和魁北克省的矿区至少有20个地震监测系统。这些矿井很多很深，挖掘深度至少达到1500米。这个项目提出了一个重大的研究工作，以发生大地震事件，或地震灾害，在加拿大深部矿山。评估地震危险性是一项复杂的任务，因为它随时间和空间的变化而变化。三名博士和两名科技学院学生将研究与地震灾害有关的五个主题。三个具有高质量地震系统和长期地震监测历史的矿井将是研究的主要重点。这些矿山分别是Agnico-Eagle的LaRonde矿、KGHM的Morrison矿和Vale的Coleman矿。将在两年内对所有三个地雷进行全面的数据收集。将采用新的和传统的地震危险性评价技术。结果将每两个月记录在报告中。这些数据将用于测试现有的地震危险性评估技术，并开发和校准新的地震危险性评估技术。重点是在大地震事件发生之前对地震危险性进行主动评估。该项目将展示加拿大采矿条件下最有前途的地震危险性评估技术。研究结果将在最后的报告中进行总结。最后报告将量化地震危险技术的成功，并讨论如何最好地将这些技术应用于加拿大的矿山。将举行两次工业讲习班，以传播项目的初步和最终结果。该项目将帮助矿山更加主动地识别和预测地震灾害。结果将改善矿山安全，提高矿山生产力，降低采矿成本。

Large seismic events are regular occurrences in deep Canadian mines. In Ontario and Quebec, statistics show that large events (magnitude = +2) are recorded almost 3 times per month. This is a common industry problem, occurring in many mines. There are at least 20 seismic monitoring systems in Ontario and Quebec mines. Many of these mines are deep, with excavations at depths of at least 1500 metres.This project proposes a significant research effort into the occurrence of large seismic events, or seismic hazard, in deep Canadian mines. Evaluating seismic hazard is a complex task, as it varies in time and space. Three PhD and two MASc students will research five topics related to seismic hazard. Three mines with high quality seismic systems and long seismic monitoring histories will be the primary focus of the research. The mines are Agnico-Eagle's LaRonde mine, KGHM's Morrison mine, and Vale's Coleman mine. Comprehensive data collection will be undertaken, at all three mines, over a two year period. New and traditional seismic hazard evaluation techniques will be employed. Results will be documented in reports every two months. This data will be used to test existing seismic hazard evaluation techniques and to develop and calibrate new seismic hazard evaluation techniques. The emphasis is on proactive evaluation of seismic hazard, i.e. before large seismic events occur. This project will demonstrate the most promising seismic hazard evaluation techniques for Canadian mining conditions.Research results will be summarized in a final report. The final report will quantify the success of the seismic hazard techniques and discuss how to best apply these techniques for Canadian mines. Two industry workshops will be held to disseminate the project preliminary and final results. This project will help mines to be more proactive about identifying and forecasting seismic hazard. The results will be improved mine safety, higher mine productivity, and lower mining costs.
