摘要： This paper studied the relationship between heavy metal concentrations of herbaceous plants and soils at four Pb-Zn mining sites in Yunnan, China. 50 herbaceous plant samples of 9 plant species from 4 families and 50 soil samples were collected and then ana1yzed for the tota1 concentrations of Pb, Cd, and Zn. The results showed that the average concentrations of Pb, Cd, and Zn in soil samples were 3772.83, 168.81, and 5385.65 mg/kg, respectively. The average concentrations of Pb, Cd, and Zn were 395.68, 28.14, and 1664.20 mg/kg in the shoots, and 924.12, 57.25 , and 1778.75 mg/kg in the roots, respectively. Heterospecific plants at the same site and conspecific plants at various sites had different average levels of Pb, Cd, and Zn, both in the shoots and the roots. Enrichment coefficients of Pb, Cd, and Zn were greater than 1 in 2, 3, and 9 herbaceous plant samples, respectively. Translocation factors of Pb, Cd, and Zn were greater than 1 in 10, 17, and 25 herbaceous plant samples, respectively. In all 50 samples, the concentrations of Pb, Cd, and Zn between the shoots and the roots, the shoots, and the soils, and the roots and the soils had significant positive relationships.

Synthesis of nanofluids composed of deep eutectic solvents and metal-modified MCM-41 particles as multifunctional

《化学科学与工程前沿（英文）》 2023年第17卷第11期页码 1776-1787 doi: 10.1007/s11705-023-2314-z

摘要： Compared with traditional hydrodesulfurization, new nonhydrodesulfurization methods have the advantage of a high removal efficiency for thiophene compounds under mild conditions. However, independent nonhydrodesulfurization technologies are faced with their own shortcomings, such as limitations of the desulfurization performance and regeneration of materials. To overcome these limitations, four nanofluids were prepared by dispersing different metal-modified MCM-41 particles in deep eutectic solvent as multifunctional promoters to develop a comprehensive desulfurization method. Based on the excellent adsorbability and high catalytic activity of the dispersed particles and the outstanding extractability of deep eutectic solvent in nanofluids, a high sulfur removal of 99.33% was achieved for model oil under mild conditions in 15 min. The nanofluids also showed excellent reusability due to their high structural stability. In addition, NF@Cu/Al-MCM-41-2.5% exhibited the best desulfurization performance among the prepared nanofluids. This result was obtained because the introduction of Al ions increased the number of acid sites and defect sites to improve the catalytic activity and adsorbability, and the best affinity of Cu/Al-MCM-41 for the deep eutectic solvent favored the reaction mass transfer. This work opens the door to the development of a comprehensive nonhydrodesulfurization method based on the design of nanofluid materials.

Micro-hydromechanical deep drawing of metal cups with hydraulic pressure effects

Liang LUO, Zhengyi JIANG, Dongbin WEI, Xiaogang WANG, Cunlong ZHOU, Qingxue HUANG

《机械工程前沿（英文）》 2018年第13卷第1期页码 66-73 doi: 10.1007/s11465-018-0468-z

摘要：

Micro-metal products have recently enjoyed high demand. In addition, metal microforming has drawn increasing attention due to its net-forming capability, batch manufacturing potential, high product quality, and relatively low equipment cost. Micro-hydromechanical deep drawing (MHDD), a typical microforming method, has been developed to take advantage of hydraulic force. With reduced dimensions, the hydraulic pressure development changes; accordingly, the lubrication condition changes from the macroscale to the microscale. A Voronoi-based finite element model is proposed in this paper to consider the change in lubrication in MHDD according to open and closed lubricant pocket theory. Simulation results agree with experimental results concerning drawing force. Changes in friction significantly affect the drawing process and the drawn cups. Moreover, defined wrinkle indexes have been shown to have a complex relationship with hydraulic pressure. High hydraulic pressure can increase the maximum drawing ratio (drawn cup height), whereas the surface finish represented by the wear is not linearly dependent on the hydraulic pressure due to the wrinkles.

Theoretical and technological exploration of deep

Heping XIE, Yang JU, Shihua REN, Feng GAO, Jianzhong LIU, Yan ZHU

《能源前沿（英文）》 2019年第13卷第4期页码 603-611 doi: 10.1007/s11708-019-0643-x

摘要： Mining industries worldwide have inevitably resorted to exploiting resources from the deep underground. However, traditional mining methods can cause various problems, e.g., considerable mining difficulty, environmental degradations, and frequent disastrous accidents. To exploit deep resources in the future, the concept of mining must be reconsidered and innovative new theories, methods, and technologies must be applied. To effectively acquire coal resources deeper than 2000 m, new theoretical and technological concepts about deep fluidized mining are required. The limits of mining depth need to be broken to acquire deep-coal resources in an environmentally friendly, safe, and efficient manner. This is characterized by ‘There are no coal on the ground and no men in the coal mine’. First, this paper systematically explains deep fluidized coal mining. Then, it presents a new theoretical concept, including the theories of mining-induced rock mechanics, three-field visualization, multi-physics coupling for transformation, and mining, transformation and transport. It also presents key technological concepts, including those of intelligent, unmanned, and fluidized mining. Finally, this paper presents a strategic roadmap for deep fluidized coal mining. In summary, this paper develops new theoretical and technological systems for accomplishing groundbreaking innovations in mining technologies of coal resources in the deep underground.

深部开采的一些挑战 Review

Charles Fairhurst

《工程（英文）》 2017年第3卷第4期页码 527-537 doi: 10.1016/J.ENG.2017.04.017

摘要：

持续增长的全球矿产供给对于满足迅速增长的世界人口的需求和期望是必不可少的。这意味着要向更深处开采。由设备供应商通过自持久R&D 研发的自动开采系统，减少了矿工暴露于恶劣的工作环境并增加了安全性。为确定矿产经济地被开采出来的深度，安全性的增长在于“地面控制”和岩石力学。尽管第二次世界大战以来，为将力学应用在采矿设计上，研究者付出了许多重要的努力，但均出现过技术和组织上的障碍。相较于大多数其他工科学科所遇到的典型工程材料，原位岩石是更复杂的一种。几千年来，采矿工程在设计上大量地依赖于经验方法。随着日益向矿山深部探索，这些方法不再适用于解决21 世纪的挑战。2008 年综合岩体模型（SRM）的发展给研究者提供了分析各向异性和不连续性岩体变形行为的能力——这些属性于1966 年被国际岩石力学学会（ISRM）的主席和创始人Leopold Müller 描述为原位岩石的本质特征。运用SRM 在大尺度采矿作业数值模拟（如崩落法）上的最新进展揭露了未预料到的岩石的变形行为。大量的平行计算和云计算技术的应用提供了许多重要机会，例如，评价数值预测中的不确定性；建立现用于岩石工程中的经验法则的力学基础及其在现有经验之上的岩体行为预测的正确性；还有在深部开采的优化设计中采用离散元法。首次，采矿和岩石工程将有其自有的基于力学的“实验室”。这有望成为在未来深部高效开采设计中的主要手段。通过在有80 多年历史的塔斯马尼亚Mount Lyell 铜矿应用采矿法反演，本文以演示实验室中DEM 和SRM 程序应用的讨论作为结束。

integrated optimization and simulation approach for air pollution control under uncertainty in open-pit metal

Zunaira Asif, Zhi Chen

《环境科学与工程前沿（英文）》 2019年第13卷第5期 doi: 10.1007/s11783-019-1156-x

摘要： Air Pollution Control model is developed for open-pit metal mines. Model will aid decision makers to select a cost-effective solution. Open-pit metal mines contribute toward air pollution and without effective control techniques manifests the risk of violation of environmental guidelines. This paper establishes a stochastic approach to conceptualize the air pollution control model to attain a sustainable solution. The model is formulated for decision makers to select the least costly treatment method using linear programming with a defined objective function and multi-constraints. Furthermore, an integrated fuzzy based risk assessment approach is applied to examine uncertainties and evaluate an ambient air quality systematically. The applicability of the optimized model is explored through an open-pit metal mine case study, in North America. This method also incorporates the meteorological data as input to accommodate the local conditions. The uncertainties in the inputs, and predicted concentration are accomplished by probabilistic analysis using Monte Carlo simulation method. The output results are obtained to select the cost-effective pollution control technologies for PM2.5, PM10, NOx, SO2 and greenhouse gases. The risk level is divided into three types (loose, medium and strict) using a triangular fuzzy membership approach based on different environmental guidelines. Fuzzy logic is then used to identify environmental risk through stochastic simulated cumulative distribution functions of pollutant concentration. Thus, an integrated modeling approach can be used as a decision tool for decision makers to select the cost-effective technology to control air pollution.
