Estimation of quartz appearance in mineral type granular materials

矿物类型颗粒材料中石英外观的估计现代生活的高质量强烈依赖于我们周围技术的不断改进和保护我们的自然。为了实现这些目标，需要长期解决环境问题，如土壤水污染、废物处置的生态问题、土壤侵蚀或埋在地下的工程设施(高压电缆、管道、人行道、储氢系统或地下放射性废物处置)的影响。上述便利设施的成功计算机设计和地面环境问题的长期解决方案需要关于土壤在各种土壤湿度、不同土壤密实度和温度范围内的热和运输特性的可靠数据。这些属性的数据库非常有限(只有几个加拿大土壤)，而且往往不完整。测量土壤导热系数既昂贵又耗时，而且容易出错。因此，建议使用基于土壤矿物学数据的预测模型，而不是使用直接测量。然而，在过去的50年里，土壤中的石英丰度并没有被测量到，它被认为是一个合适的参数。因此，该项目的重点是测量代表每个省和地区的加拿大土壤的矿物学成分和土壤导热系数。收集到的数据将用于开发一种全球预测模型，该模型将应用于地下热湿流动的计算机建模。此外，加拿大土壤的加入将加强现有的土壤热学和水力性质预测的计算机程序包，从而根据容易获得的数据提供可靠的估计。用于现场测量的便携式热导探头的开发也是该项目的一部分。所获得的专门知识将与地球科学和工程部门分享，涉及土壤的环境问题或土工利用。

Estimation of Quartz Appearance in Mineral Type Granular MaterialsThe high quality of modern day life depends strongly on the continuous improvement of the technology surrounding us and preserving our nature. To achieve these objectives, a long-term solution is needed to environmental issues, such as soil water pollution, ecological problems of waste disposal, soil erosion, or impacts of engineering facilities buried in the ground (high-voltage power cables, pipelines, pavements, hydrogen storage systems, or underground radioactive waste disposal). The successful computer design of the above amenities and long-term solutions to environmental issues of the ground require reliable data concerning the thermal and transport properties of soil over a full range of soil wetness, variable soil compactness and temperature. The database of these properties is very limited (a few Canadian soils only) and often incomplete. Measuring soil thermal conductivity is expensive, time consuming, and error prone. Therefore, instead of using direct measurements, the use of predictive models based on soil mineralogical data is recommended. Over the past 50 years, however, the quartz abundance in soils was not measured and it was assumed as a fitting parameter. Therefore, the project is focusing on measurements of soil mineralogical composition and soil thermal conductivity of Canadian soils representing each province and territory. The gathered data will be used for the development of a global predictive model to be applied in computer modeling of heat and moisture flow in the ground. Furthermore, the existing computer package dealing with prediction of soil thermal and hydraulic properties will be enhanced by addition of Canadian soils, thus providing reliable estimates based on easily obtainable data. The development of a portable thermal conductivity probe for field measurements is also a part of this project. Expertise gained will be shared with the geo-science and engineering sector dealing with the environmental aspects or geotechnical utilization of soils.
