某露天关闭矿山地质环境综合治理的实践

Practice of Geological Environment Control in an Open Pit Closed Mine

论文以江苏某露天开采砂岩关闭矿山地质环境治理为例,在对矿山边坡地质环境条件分析的基础上,通过现场地质调查,边坡稳定性评价等方法,对开采边坡存在的关键工程地质问题进行了分析。针对露采高边坡不同区域地质灾害特征及潜在危害,结合该关闭矿山宕口的利用要求,提出了分区采用清除危岩、削坡减载、随机锚杆、柔性防护网及排水等措施进行边坡消灾治理,有效的保障了宕口作为垃圾填埋场施工与运行期的安全。

Taking the geological environment management of an open-pit sandstone mine in Jiangsu province as an example based on the analysis of the geological environment conditions of the mine slope, the paper analyzes the key engineering geological problems of the mining slope by the methods of field geological investigation and slope stability evaluation. According to the characteristics and potential hazards of geological disasters in different areas of open mining high slope, combined with the utilization requirements of the shut-down mine, the paper puts forward some measures such as local removal of dangerous rock, random anchor bolt, flexible protective net and drainage to carry out the slope disaster elimination treatment, which effectively guarantees the safety of the shut-down as a rubbish landfill during the construction and operation period.
