Abstract :
基于生态足迹和碳足迹理论,提出能源足迹的概念与计算方法.以福州市为例,分别按能源种类和工业行业计算了该市 2011-2020 年能源足迹及其强度,对这 10 年能源足迹变化趋势做了分析,运用STIRPAT模型及岭回归分析方法进行了预测,并按照高速和基准两个情景对能源足迹分别进行了分析和预测.研究表明,福州市 2011-2020 年能源足迹呈现波动下降又回升趋势,能源足迹强度则整体呈现下降趋势,能源结构不断优化;福州市要实现 2030 年碳达峰情景,能源足迹强度每年需降低 4.1062%(按研究期的水平).福州市应继续坚持生态城市和数字城市的发展目标,从能源种类上看应该大力发展风能、水利、天然气、太阳能、核电等可再生能源;从工业结构上则要做强计算机、通信和其他电子设备制造业.本研究对于城市产业结构优化、碳排放目标实现均有一定的理论参考价值和现实意义.

Abstract :
Blasting is the primary technical method of mining mineral resources, the accurate prediction of blasting fragmentation after blasting has a key impact on controlling mining operation costs and reducing environmental pollution. To that end, a powerful artificial intelligence (AI) model, named Gaussian Process Regression (GPR), was proposed to predict the mean fragment size (MFS) of broken rock after blasting. To improve the prediction performance of GPR model, the newly bio-inspired Artificial Hummingbirds Algorithm (AHA) was employed to select the optimal hyperparameter's combinations. Additionally, the other regression models including the artificial neural networks (ANN), support vector regression (SVR), and standard GPR, were also developed to compare the prediction performance with the proposed hybrid AHA-GPR model. Two cases collected from Chilean copper mine and an Indian coal mine were used to verify the model performance, mainly using two performance metrics and the Taylor diagram analysis to determine the best prediction model. The AHA-GPR model achieved R-2 values of 0.88 and 0.85, with RMSE values of 11.40 and 9.50 for the Copper mine database, and R-2 values of 0.93 and 0.90, with RMSE values of 0.02 and 0.03 for the Coal mine database. These results demonstrate that the AHA-GPR model outperforms other predictive models, establishing it as the most reliable approach in both case studies. Besides, this AI model-based approach offers researchers and mining engineers an improved approach to predict the rock fragmentation after blasting, facilitating thorough analysis of blasting design before mining operations and enabling precise forecasting of blasting outcomes. Furthermore, the sensitivity analysis further provided essential insights to optimize the blasting designs.

Abstract :
The construction of mining parks is an important way to restore and manage the ecological environment of mines, and the assessment of the soil remediation effect of mine parks is of great significance to the construction and operation of mining parks and the safety of tourists. 66 soil samples were collected from 0-30 cm of dry soil on unhardened ground in the mining park, and the contents of heavy metals Mn, Cr, Zn, Pb, As, Cu, Ni and Hg were measured. The comprehensive pollution index, potential ecological risk index and health risk assessment model were used to evaluate pollution status, potential ecological risk and human health risk of the remediated soil. The results showed that the average values of each metal element in M Mining Park were Mn > Cr > Zn > Pb > As > Cu > Ni > Hg, where the average values of Cr, Mn, Cu, As and Pb were 1.23, 1.80, 1.12, 2.05 and 1.34 times of the background values of Hunan soil, respectively. The Nemerow comprehensive pollution index was 0.51, which was at a safe level. The single factor potential risk index for each heavy metal element was at the low ecological risk level, and the average potential ecological risk index was 81.64, which was at the low ecological risk level, showing there was no potential ecological risk. The total non-carcinogenic risk value for children and adults was respectively 2.46×10−1 and 7.43×10−2, which did not cause non-carcinogenic risk, and the total carcinogenic risk index was 1.38×10−7, which did not have carcinogenic risk. Overall, after ecological restoration, the mine park would have no ecological risk and health risk of heavy metals in soil, suitable for tourism and recreation for various populations. © Journal of Central South University (Medical Science).

Abstract :
传统的专业课教学以教师讲授为主,学生被动接收,学习效果不理想.引入基于文献探究的研讨式教学法,即从文献搜集和研读人手,针对专业课程内容涉及的领域方向进行拓展学习和训练,通过文献综述写作、组织专题研讨等学习方式不仅加深了学生对所学专业知识的理解和灵活应用,也培养和训练了其独立学习和沟通合作的能力.本文以福州大学紫金矿业学院开设的“矿业经济学”采矿专业课为例,探讨和分析了该法在教学实践中的应用情况.
