对我们的设施和程序进行内部和外部审查,以确保我们保持最高的安全和环境保护标准,包括遵循MAC和ICMM制定的最佳实践指南。除了全面的内部和外部审查外,我们还通过我们的尾矿工作组对我们的尾矿设施进行了额外级别的设施监督,该工作组包括来自我们各业务部门和现场的主题专家。该工作组还保存了Teck自己的尾矿指导和治理框架文件。
内部Reviews
Staff Inspections
尾矿坝由训练有素的操作人员和专业技术人员每天检查几次,正式人员每月至少检查一次。
yabo国际娱乐尾矿治理审查
yabo国际娱乐尾矿治理审查在我们的运营中每两年进行一次,在我们的遗产中每三年由内部主题专家进行一次。这些治理审查包括确认我们有适当的人员和程序来履行我们的承诺,以及我们正在以有意义和及时的方式从外部审查中提出持续改进的建议。
治理审查还评估了我们的记录工程师和其他外部审查人员的绩效,以寻找泰克以外的人是否自满或缺乏继任规划的迹象,这些人是我们整个管理流程的一部分。对于我们的合资项目,我们与Antamina矿和Fort Hills油砂矿的其他股东有一个持续的流程,符合我们治理审查流程的要求。
From the combined Governance Review process in 2019, there were no significant findings; however, several value-added items were identified and are being actioned by the sites. As a result of our ongoing Tailings Governance Review processes and based on themes from the MAC and ICMM advancements, we are further strengthening our guidance related to change management, roles and responsibilities, enhancing integration of risk evaluation and identifying critical controls.
外部评审
大坝安全检查and Dam Safety Reviews
A fully licensed, qualified individual who is vetted by our Tailings Working Group conducts formal dam safety inspections (DSIs) at least annually. Independent, qualified engineers also conduct periodic reviews, with timing dependent upon the consequence classification of the facility. For all facilities, the annual inspection reports are provided to the appropriate authority in each jurisdiction. DSIs and Dam Safety Reviews are conducted to evaluate our conformance with international best practices, our internal policy/standards and applicable regulatory requirements. Teck makes DSIs and other information about our tailings facilities, both operating and legacy, available on our website at网址:m.zaojianmedia.com/tailing.
Independent Review Boards
A key element of Teck’s review process is the use of Independent Review Boards. These boards, typically comprising three very senior subject matter specialists, meet from once to several times per year, depending upon the nature of the facility and the issues being considered by the board, to conduct a third-party review of design, operation, surveillance and maintenance of our storage facilities. The results from the Review Board assessments are communicated directly to senior management.
Additional Detailed Third Party Reviews
一个合格的独立尾矿评论家,审查by our Tailings Working Group, conducts comprehensive third-party dam safety reviews every three to 10 years for active and inactive facilities. The frequency of inspection is based on the consequence classification for each facility.
Tailings Reviews Conducted in 2019
All of our operating and legacy facilities are reviewed against our internal policy and guidance documentation on a regular schedule, as described in Table 17.

记录工程师对设施及其相关基础设施和与之相关的记录进行详细检查,以确定可能对结构的安全性和可靠性造成危害或发出潜在危害信号的任何条件或变化。
由独立的第三方工程师进行的设施审查,不隶属于记录工程师或尾矿审查委员会。这些审查的频率取决于该结构的故障后果风险评级。
Review by a team of independent senior subject matter experts who review the facility design approach, surveillance results and a site’s overall approach to tailings management, including performance of the Engineer of Record.

Special Reviews
除了内部和外部审查外,泰克还将偶尔完成一次特别审查。波利山事件(2014年)和萨马尔科事件(2015年)都引发了这样的评论。2019年,针对巴西Brumadinho的惨败,Teck对其尾矿和蓄水结构进行了特别独立审查,包括向董事会安全和可持续发展委员会报告的上游和更高后果设施。这项特别审查包括三名外部高级主题专家,分三个阶段进行:
- 第一阶段:桌面确认泰克的运营、遗留尾矿和蓄水结构以及主要项目的所有后果分类和风险等级。
- 第2阶段:评估被评估设施的技术设计和管理的有效性,特别关注设施事件触发、紧急警报/响应和专职人员的关键控制,包括能力和能力/培训。
- 第3阶段:访问第2阶段的选定站点,回答外部评审员的问题。这一阶段的结果是对更优先的设施进行最终评估,其中包括审查故障事件的剩余风险和随后的生命损失或环境损害,同时考虑到尾矿和蓄水构筑物下游人员的潜在位置。
审查的结论是,在泰克的尾矿和水坝内,没有明显的灾难性故障的直接或新出现的威胁。
