Occurrence and health risk assessment of trace heavy metals via groundwater in Shizhuyuan Polymetallic Mine

Bingbing XU,Qiujin XU,Cunzhen LIANG,Li LI,Lijia JIANG

《环境科学与工程前沿（英文）》 2015年第9卷第3期页码 482-493 doi: 10.1007/s11783-014-0675-8

摘要： The Shizhuyuan Polymetallic Mine in Chen-zhou City is an important multi-metal deposit in China. After a dam accident in 1985, there are still a number of mining plants, smelters and tailing ponds in this area. These had the potential to pollute the surrounding groundwater. In this study, groundwater samples were collected from 20 residents’ wells in this area during both dry and wet seasons. In particular, this study focused on the exposure and the health risk assessment of trace heavy metal in groundwater. Multiple statistical analysis and fuzzy comprehensive method were employed to reveal the distribution characteristics of heavy metal and to assess the groundwater quality. Results indicated that Cr, Fe, Ni, Cu, Zn, As, Cd, Ba, Hg and Pb were widespread with low exposure levels. There were 19 wells with low level exposure and one well with a moderate level exposure in the dry season. All of the wells were in low level exposure during the wet season. As and Mn exhibited potential non-carcinogenic concern, because their maximum hazard quotient (HQ) was higher than 1.0. This may cause adverse health effect on adults in dry season or on children in both seasons. Only As, showed that the maximum carcinogenic risk was more than 10 , suggesting a high cancer risk for children in both dry and wet seasons. Therefore, analysis and reduction the concentrations of As and Mn in groundwater are needed in order to protect the health of residents and especially children in the area.

Technology Development and Engineering Practice for Protection and Utilization of Water Resources in Coal Mining in Western China

Da-zhao Gu

《工程管理前沿（英文）》 2016年第3卷第1期页码 59-66 doi: 10.15302/J-FEM-2016010

摘要： Shanxi, Shaanxi, Inner Mongolia, Ningxia, and Gansu (hereafter generally referred as “the Western Area”) are major coal-producing areas in China due to rich coal resources and good mining conditions. However, the Western Area has a serious water shortage. The surface evaporation is huge and a great amount of mine water generated in coal mining is evaporated and lost after discharging to surface. In order to protect and utilize the water resources during large-scale coal mining in the Western Area, Shenhua Group has put forward a technological idea to store mine water in underground mined areas and successfully researched and developed the coal mine underground reservoir technology by solving the technical difficulties of water source prediction, reservoir site selection, reservoir capacity design, dam construction, safety guarantee, water quality control and so on through 20 years of exploration. Now Shenhua Group has successfully established a batch of reservoir in the Shendong Mining Area, obtaining great economic and social benefits. The technology is also extended to other western mining areas, providing an effective path for harmonic mining of coal and water resources in western China.

矿山安全减灾系统科学——矿山灾害学

周利华

《中国工程科学》 2003年第5卷第7期页码 90-94

摘要：

矿山灾害学是一门综合性强并需不断扩充的矿山安全减灾科学。它与以往单一矿山灾害防治理论研究相比，具有综合性、预测性和经济性三大特征；它的安全减灾原理包含了安全哲学、安全经济学等八大原理；它的研究模型体现了宏观与微观相统一的原则。因此，矿山灾害学的研究，应以科学的系统论思想为指导，采用逻辑与历史相统一法，既要从微观上研究矿山灾害中单一灾种事故的防治技术和方法，又要在宏观上从不同学科、不同层次、不同的方位切入，对矿山灾害进行系统的研究；与此同时，还必须大力开展多层次、多领域、多方位的国际协作。

大屯矿区深部软岩巷道非对称变形机理及控制对策研究

傅清国,邹朝阳

《中国工程科学》 2011年第13卷第11期页码 102-106

摘要：

通过对孔庄矿工程地质情况调查与分析，结合室内岩石力学实验，运用三维数值模拟方法，研究巷道非对称变形时周围岩体的位移场分布规律，分析巷道推进到上部工作面下方时的应力分布规律。理论研究结果表明，孔庄矿－785 m水平轨道大巷非对称变形主要受其上部采空区煤柱的集中压力控制，黏土矿物遇水膨胀、岩层结构及高地应力作用进一步恶化了巷道围岩结构。该研究可为孔庄矿深部巷道非对称变形控制对策提供初步的理论依据。

摘要： Iron ore is necessarily basic raw material for industrialization and urbanization and related to the industrial distribution and development programming. The lean iron ore resource in our country is high-cost and low-efficiency, which cannot meet the demand of iron and steel industry, and even endanger the safety of industrial economy. Ansteel mining has created “grade decision-based multi-system integration” mode of mining and metallurgy system engineering and realized scale and efficient development of lean iron ore on basis of the construction of digital mines. Moreover, the “wisdom mines” was proposed and had led to the transformation and upgrading of iron developments.

Kehui Liu, Xiaolu Liang, Chunming Li, Fangming Yu, Yi Li

《环境科学与工程前沿（英文）》 2020年第14卷第6期 doi: 10.1007/s11783-020-1279-0

摘要： Abstract • The soil TP level was high or extremely high in all areas. • TN, OM and available Cu were insufficient in EA, TA and RA. • All areas reached the heavily polluted level and had high ecological risk levels. • Mn and Cd were the dominant pollutants. Nutrient status and pollution levels are the main factors affecting soil restoration. The nutrient status and pollution levels in five areas, an unexplored mine area (UA), an explored mine area (EA), a tailings area (TA), a reclamation area (RA) and an agricultural area (AA), around the Pingle manganese mine in Guangxi, China, were assessed in this study. The results showed that the average total phosphorus in these five areas ranged from 1.05 to 1.57 mg/kg, corresponding to grades of extremely high and high. The average total nitrogen values were 0.19, 0.69, 0.93, 1.24 and 1.67 mg/kg in EA, TA, RA, UA and AA, corresponding to grades of very low, low, medium-low, medium-high and medium-high, respectively. The average organic matter values were 12.78, 8.92, 22.77, 21.29 and 29.11 mg/kg in EA, TA, RA, UA and AA, which corresponded to grades of medium-low, low, medium-high, medium-high and medium-high, respectively. All these results indicated that the total phosphorus was sufficient in these areas, while the total nitrogen and organic matter were insufficient in EA, TA and RA. The available concentrations of Mn and Zn corresponded to the intermediate grade, while the values for Cu corresponded to the very low grade; these might be another factor restricting ecological reclamation. Contamination and ecological risk assessments based on the single contamination index, Nemerow multi-factor index and potential ecological risk index showed that the five tested areas around the Mn mine were considered heavily polluted and presented high ecological risk. Mn and Cd were the dominant pollutants.

YANG Shengxiang,LIANG Shichu,YI Langbo,XU Bibo,CAO Jianbing,GUO Yifeng,ZHOU Yu

《环境科学与工程前沿（英文）》 2014年第8卷第3期页码 394-404 doi: 10.1007/s11783-013-0602-4

摘要： Screening plants that are hypertolerant to and excluders of certain heavy metals plays a fundamental role in a remediation strategy for metalliferous mine tailings. A field survey of terrestrial higher plants growing on Mn mine tailings at Huayuan, Hunan Province, China was conducted to identify candidate species for application in phytostabilization of the tailings in this region. In total, 51 species belonging to 21 families were recorded and the 12 dominant plants were investigated for their potential in phytostabilization of heavy metals. Eight plant species, , , , , , , , and accumulated much lower concentrations of heavy metals in shoots and roots than the associated soils and bioconcentration factors (BFs) for Cd, Mn, Pb and Zn were all<1, demonstrating a high tolerance to heavy metals and poor metals translocation ability. The field investigation also found that these species grew fast, accumulated biomass rapidly and developed a vegetation cover in a relatively short time. Therefore, they are good candidates for phytostabilization purposes and could be used as pioneer species in phytoremediation of Mn mine tailings in this region of South China.
