The proposed research program will investigate the classification of mined oil sands material as ore or waste on the basis of technical and economic criteria. The oil sands are the largest commodity in the Canadian mining industry in terms of both waste material mined and ore material processed. They are also the largest source of tailings waste in Canada. Oil sands mining operations are subject to static criteria when determining whether mined material is ore or waste, i.e. whether material should be sent to the processing plant for bitumen recovery or sent to a waste dump. These criteria are uniform for all operations and established by a provincial regulation, Alberta's Interim Directive 2001-7. The definition of ore by regulation is unusual internationally, and unique to the oil sands within Canada. The research program will produce an analysis of the impact of the current prescribed oil sands mine planning system versus an engineering approach to defining mining pit limits and mined material classification as ore or waste. The analysis will define the impacts of the two methods on project economics, bitumen resource conservation and utilization, and environmental impact, including accrued environmental liability. The research will include sub-activities exploring the costs associated with oil sands mining. The focus will be on linking environmental impacts and their associated costs (terrestrial and aquatic reclamation and tailings treatment) to the specific material qualities of processed ores. The research program will address concerns related to oil sands reclamation liabilities expressed by the public, non-governmental organizations, other oil sands stakeholders, and First Nations. The research has the potential to inform and influence regulations related to oil sands mining. If the hypothesis of the research program is correct, it is anticipated that the analysis will form the basis for policy reform recommendations. Improved environmental performance of oil sands operations with respect to tailings waste production is a long-term objective of the research. The anticipated outcomes of the research program include: -Improved understanding of the costs associated with oil sands land reclamation by extending the applicant’s current research in this area -Improved understanding of the costs associated with oil sands tailings treatment methods, and the first work in the public domain in this area -The first work in the public domain to attempt to quantify tailings waste production associated with different material qualities (bitumen grade, fines content, clay content, etc.) of oil sands materials -An analysis of the impact of the existing regulations on: economic performance of oil sands operations; waste production by oil sands operations (mined and tailings waste); accrued liability related to tailings; and bitumen resource utilization and conservation -A critical review of the existing regulations with respect to their ability to meet stated goals of responsible resource development and resource conservation. The research program will provide training in advanced mine planning methodologies for 5 HQP. These HQP will develop: -Advanced knowledge of the principles of strategic mine planning -Practical skills in the application of mining software -Advanced knowledge of mining systems and the relationships between activities in the system -The ability to create sophisticated mining cost models, including models that incorporate explicit consideration of externalities into the mine planning process -The ability to develop mine plans that incorporate principles of sustainable planning -The ability to critically assess the influence of regulatory and other constraints on mine planning outcomes.

拟议的研究计划将根据技术和经济标准调查开采的油砂材料是矿石还是废物的分类。油砂是加拿大采矿业中最大的商品，包括开采的废料和加工的矿石材料。它们也是加拿大最大的尾矿废物来源。 油砂开采作业在确定开采的材料是矿石还是废料时，即材料是否应被送到加工厂进行沥青回收或送到废料场时，受到静态标准的限制。 这些标准对所有业务都是统一的，并由一项省级条例-阿尔伯塔第2001-7号临时指令-规定。矿石的定义在国际上是不寻常的，在加拿大的油砂中是独一无二的。 该研究计划将分析当前规定的油砂矿规划系统与工程方法的影响，以确定采矿坑限制和开采材料分类为矿石或废物。分析将确定这两种方法对项目经济、沥青资源保护和利用以及环境影响（包括应计环境责任）的影响。该研究将包括探索与油砂开采相关的成本的子活动。 重点将是将环境影响及其相关费用（陆地和水生填海以及尾矿处理）与加工矿石的具体材料质量联系起来。 该研究计划将解决公众、非政府组织、其他油砂利益相关者和原住民对油砂回收责任的担忧。这项研究有可能为油砂开采相关法规提供信息并产生影响。 如果研究计划的假设是正确的，预计分析将成为政策改革建议的基础。改善油砂作业在尾矿废物生产方面的环境绩效是这项研究的一个长期目标。 研究计划的预期成果包括： - 通过扩展申请人在该领域的现有研究，提高对油砂土地复垦相关成本的理解 - 提高对油砂尾矿处理方法相关成本的认识，并在这一领域开展第一项公共领域的工作 - 公共领域的第一项工作，试图量化与不同材料质量（沥青等级，细粒含量，粘土含量等）相关的尾矿废物生产。油砂材料 - 分析现有法规对以下方面的影响：油砂作业的经济效益;油砂作业产生的废物（开采废物和尾矿废物）;与尾矿有关的应计负债;沥青资源利用和保护 - 严格审查现行条例是否有能力实现负责任的资源开发和资源保护的既定目标。 该研究计划将为5名HQP提供先进的矿山规划方法的培训。这些HQP将开发： - 对战略地雷规划原则的深入了解 - 应用采矿软件的实用技能 - 对采矿系统和系统中活动之间的关系有深入了解 - 能够建立复杂的采矿成本模型，包括在采矿规划过程中明确考虑外部因素的模型 - 有能力制定纳入可持续规划原则的采矿计划 - 有能力严格评估规章和其他限制因素对采矿规划结果的影响。
