Highlights

After years of exploration and development,the surrounding environment of the gold mine in Laizhou ore concentration area has been changed and destroyed in varying degrees.In order to find out the environmental geological problems caused by Cangshang gold mine in Laizhou mining area,the high density resistivity method was applied to carry out section survey in the northeast side of Cangshang gold mine.The results of the investigation preliminarily identified the environmental geological problems,such as the stratigraphic geoelectric characteristics of the northeast side of Cangshang gold mine,the distribution of hidden fault structures and the underground goaf,and the extent of underground seawater intrusion.Through this investigation,the following insights have been gained:(1)The high density resistivity method can effectively identify the seawater intrusion in the northern part of Cangshang gold mine,and the seawater intrusion in the northern part of the mine is strong in the east and weak in the west.(2)The high density resistivity method can accurately identify the spatial distribution and structural water content of the hidden Sanshandao fault,which indicates that the Sanshandao fault slows down the seawater intrusion trend in Laizhou bay.(3)The high-density resistivity method can accurately identify the distribution range,strike,burial depth,water filling conditions and spatial morphology characteristics of the goaf.(4)The high density resistivity method can improve the working efficiency and is an effective method for environmental geological survey of ore concentration area,which can provide a good reference and guidance for environmental geological survey of similar areas.

我国有色金属工业迎来多重利好

“2023年有色金属工业生产总体仍会保持平稳运行,预计10种常用有色金属产量增幅在3.5%左右,有望突破7 000万t;工业增加值增速在4.5%左右。”在2022年有色金属工业运行情况新闻发布会上,中国有色金属工业协会党委常委、副会长、新闻发言人陈学森表示,从全球经济环境和国内环境来看,2023年,我国有色金属工业迎来多重利好,行业将保持平稳运行。

2023年有色金属工业固定资产投资增幅有望保持在5%~10%之间。铜铝等矿山原料进口将保持稳定或略有增加,但铝材出口增幅减缓是大概率事件。有色金属价格或呈稳中有降趋势。预计有色金属工业企业全年实现利润3 000亿元左右。

2022年,我国有色金属工业沉着应对风险挑战,奋力完成改革发展稳定任务,呈现平稳向好态势。2023年,一系列稳增长政策将逐步显效,支撑有色金属工业平稳运行。光伏、风电等可再生能源的发展将进一步拉动铝、工业硅、稀土等有色金属需求;电动汽车、新能源电池及储能设备等产业的快速发展,也在不断提高铜、铝、镍、钴、锂等金属的应用。此外,铝材消费有望回稳。2023年,房地产业下行趋势有望缓解,建筑、家电等行业对铝材的需求,尤其是对建筑铝型材需求的收缩将有所改观,加上以新能源汽车、光伏行业为代表的新兴领域对铝材需求提升,我国铝材需求规模有望回稳。

推进高质量绿色发展是有色金属工业的重要任务之一。2022年,按照低碳先行、源头预防、过程控制、末端治理、绿色引导的原则,有色金属工业在原有的节能与绿色标准体系基础上,构建了由“节能与综合利用、绿色评价和双碳”3个标准子体系共同构成的绿色低碳标准体系,以推动高质量绿色发展。

为了早日实现有色金属行业碳达峰目标,工业和信息化部、国家发展改革委、生态环境部三部门联合印发《有色金属行业碳达峰实施方案》,旨在科学把握碳达峰路径,围绕产能控制、产业结构优化、绿色低碳技术研发、能源结构优化、绿色制造体系建立等重点任务,扎实推进严控冶炼产能总量、大力推进产业结构转型升级、加强绿色低碳技术创新和推广应用、推进可再生能源替代、建设绿色制造体系5项重点工作。
