项目摘要

This project will develop a preliminary design and work-breakdown-structure for a large-scale subsurface experimental facility to investigate coupled thermal-hydrological-mechanical-chemical-biological processes in fractured rock at depth. The experiment will be part of the proposed Deep Underground Science and Engineering Laboratory (DUSEL) in the Homestake Mine, South Dakota. Many natural and engineered earth systems involve coupling of multiple processes in rocks that vary across a wide range of scales. The most pervasive process in the Earth?s crust that gives rise to strongly coupled phenomena is the flow of fluids (water, CO2, hydrocarbons, magmas) through fractured heated rock under stress. Understanding changes in the reactivity, deformability, life-supporting and transport properties of rocks that fluids infiltrate is important in a broad range of geological engineering and geological science endeavors. Despite this fundamental importance, the interactions remain poorly understood.The project will: (1) Determine properties of Homestake rocks: geological, geochemical, mechanical, thermal, isotopic, and reactivity. (2) Upscale these data to elucidate transport mechanisms (conductive versus convective), natural reaction rates in fractures, and microbial community evolution. (3) Evaluate monitoring strategies, in-situ probes and sampling methods, and necessary measurements. (4) Select a candidate site for the evaluating coupled processes. (5) Develop a work-breakdown-structure. (6) Develop a coupled numerical model to evaluate potential effects on the rock mass and optimal heater configuration, power, and monitoring borehole orientations.The models and insight from these experiments will have broad applicability to engineered systems, e.g., enhanced geothermal systems, CO2 sequestration and subsurface contaminant transport. Educational outreach will involve facility tours and a traveling benchscale ?mock-up? demonstration experiment.
该项目将为一个大型地下实验设施开发初步设计和工作分解结构,以研究深部断裂岩石中的耦合热-水文-力学-化学-生物过程。该实验将是拟议中的位于南达科他州霍姆斯特克矿的深层地下科学与工程实验室(DUSEL)的一部分。许多自然和工程地球系统涉及岩石中多种过程的耦合,这些过程在很大范围内变化。地球上最普遍的过程?在地壳中引起强耦合现象的是流体(水、CO2、碳氢化合物、岩浆)在应力作用下通过破裂的热岩的流动。了解流体渗透岩石的反应性,变形性,生命支持和运输特性的变化在广泛的地质工程和地质科学工作中非常重要。本计画将:(1)确定Homestake岩石的性质:地质、地球化学、机械、热、同位素和反应性。(2)放大这些数据以阐明传输机制(传导与对流)、裂缝中的自然反应速率和微生物群落进化。(3)评估监测策略、现场探头和取样方法以及必要的测量。(4)为耦合过程的评价选择一个候选场地。(5)制定工作分解结构。(6)开发一个耦合的数值模型,以评估对岩体的潜在影响,并优化加热器配置、功率和监测钻孔方向。这些实验的模型和见解将广泛适用于工程系统,例如,强化地热系统、二氧化碳封存和地下污染物迁移。教育推广将包括设施图尔斯和旅行台秤?模型?演示实验
