近年来,社会经济的发展使得生产生活中对矿产资源的客观需求量大幅度增大,新矿山大量开发意味着废弃矿山增多。实践中可以看到,大量废弃矿山的出现,对本地环境条件以及地质状况等造成了严重的影响。本文主要分析了废弃矿山对环境地质造成的主要灾害类型进行分析,并在此基础上就如何进行防治进行探讨。 相似文献

张家口市矿产资源丰富,是河北省矿产资源大市之一。由于矿产资源的不合理开发利用,引发了各种各样的矿山地质环境问题,矿山地质环境保护与恢复治理任务十分艰巨。张家口战略地位十分独特,既是北京的主要饮用水源地,又是西部和北部风沙侵入京津的两条通道,张家口的生态环境严重影响和决定着首都北京的生态环境。京津冀协同发展、建设“首都水源涵养功能区和生态环境支撑区”和北京市携手张家口承办“2022年冬奥会”的3个重大历史机遇,也倒逼张家口必须尽快修复和治理各类矿山环境地质问题,促进张家口转型升级、绿色崛起。通过分析张家口矿产资源利用现状和主要的矿山地质环境问题分类,从矿山地质环境管理、生态修复治理的政策、思路、资金渠道和技术方法方面为矿山环境修复治理提供了对策。 相似文献

Changes in water quality over 25 years have been documented for discharges from an extensive network of abandoned underground coal mines in the Uniontown Syncline, Fayette County, PA, USA. A baseline study of 136 mine discharges in the syncline was conducted in 1974-1975. In 1998-2000, follow-up water flow and quality monitoring was conducted at 21 selected discharges for 2 years to assess the degree of mine water-quality improvement since 1974-1975. The data from the two periods of time were compared, with consideration of differences in measurement methods. The degree and rate of water-quality improvement was found to be highly dependent on the amount and duration of flooding in the mine voids. Water quality of discharges from the substantially flooded mine voids improved significantly, going from acidic water with high sulfate and iron concentrations in 1974-1975 to alkaline water with substantially lower sulfate and iron concentrations in 1998-2000. In contrast, the water quality in the unflooded mines showed less improvement over the 25 years between studies. The water discharging from the unflooded mines in 1974-1975 was acidic with high sulfate concentrations and in 1998-2000 was still acidic but showed somewhat lower sulfate and iron concentrations, reflecting depletion of readily available pyrite. The data obtained provide insight into the potential and rate of natural amelioration of mine water quality in different abandoned underground coal mine systems. 相似文献

Reclamation of abandoned open mines with innovative meandrically arranged geotextiles 总被引:1,自引:0,他引:1
《Geotextiles and Geomembranes》2020,48(3):236-242
For over fifty years, geosynthetics have been used for land reclamation of degraded areas. Several years ago for this purpose innovative geotextiles formed from meandrically arranged thick ropes were invented. The geotextiles were used for reclamation of abandoned lignite open-mine in Germany and disused gravel pit in Poland. The geotextiles were installed in abandoned mines. In next years positive influence of geotextiles on slopes behaviour and vegetation was observed. It was stated that the geotextiles provide stabilization of steep unstable slopes and significantly accelerate vegetation development. The innovative geotextiles perform functions unobtainable for other traditional products. The products are useful in an effective reclamation of open mines and constitute a valuable extension of the geosynthetic assortment applicable in land reclamation. 相似文献
