Data driven seismic hazard evaluation in Canadian mines

加拿大深井中经常发生大地震事件。在安大略省和魁北克省，统计数据显示，大型地震(震级=+2)几乎每月记录3次。这是一个常见的行业问题，在许多煤矿都会发生。安大略省和魁北克省的煤矿至少有20个地震监测系统。其中许多矿井都很深，挖掘深度至少有1500米。该项目建议对加拿大深层矿井中发生的大地震事件或地震危险进行重大研究。评估地震危险性是一项复杂的任务，因为它在时间和空间上都是不同的。三名博士生和两名MASC学生将研究与地震危险有关的五个主题。具有高质量地震系统和长期地震监测历史的三个矿井将是研究的主要重点。这些矿场是Agnico-Eagle的LaRonde矿、KGHM的莫里森矿和淡水河谷的Coleman矿。将在所有三个矿场进行为期两年的全面数据收集。将采用新的和传统的地震危险性评估技术。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。重点是地震危险性的主动评估，即在大型地震事件发生之前。该项目将展示加拿大采矿条件下最有前景的地震危险性评估技术。研究结果将在最终报告中总结。最终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。将举办两次行业讲习班，以传播项目的初步和最终成果。该项目将帮助矿山更加积极主动地识别和预测地震危险。其结果将是改善矿山安全，提高矿山生产率，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.
