淮南市矿山地质环境问题及防治技术研究

淮南市是中国重要的资源型城市之一,长期的矿产资源开采形成了含水层破坏、采空塌陷、岩溶塌陷、地形地貌景观破坏、水土环境影响等一系列矿山地质环境问题。通过对淮南矿山地质环境调查成果进行研究分析,总结矿山地质环境问题的特征及影响因素。以含水层破坏防治为例,系统总结以留设防水煤岩柱、长期观测水位、加强污水处理为手段的综合防治技术,该技术的采用不仅减轻了开采对含水层的破坏,而且实现了含水层破坏的有效防治。

Research on Mine Geological Environmental Problems and Prevention Techniques in Huainan City

Huainan City is one of the important resource-based cities in China,the long time mining of mineral resources has formed a series of mine geological environment problems such as aquifer destruction,goaf collapse,karst collapse,topography landscape destruction,water and soil environmental impact etc.The paper studies and analyzes the results of the mine geological environment investigation in Huainan City,summarizes the characteristics and influencing factors of the mine geological environment problems.Take the prevention and control of aquifer damage for example,the authors systematically summarize the comprehensive prevention and control technology of retaining waterproof coal pillars,observing water level for a long time,and strengthening sewage treatment.The technology not only reduces the damage of aquifer by mining,but also achieves effective prevention and control of aquifer damage.
