豫安煤矿开采对矿山地质环境影响及治理技术

The impact of Yu′an Coal Mine mining on the geological environment of mines and its treatment techniques

为了改善豫安煤矿矿山地质环境,减轻煤矿开采引发的地质灾害,修复地貌景观和土地资源,对该矿山地质环境影响进行了评价。研究区主要地质灾害为地面塌陷、地裂缝,采矿活动没有破坏含水层或对含水层的影响破坏较轻,对原生地形地貌景观破坏程度较大,矿山活动对土地资源破坏程度严重。基于此,提出了矿山地质环境综合治理技术,包括场地平整技术、道路技术、排水渠技术、绿化技术、土壤培肥与翻耕、管护技术等。研究可最大限度地避免或减轻采矿活动对矿山地质环境的影响和破坏,实现矿山地质环境的有效恢复。

In order to significantly improve the geological environment of Yu′an Coal Mine,reduce the geological disasters caused by coal mining,repair the geomorphic landscape,and restore land resources,the impact of the geological environment of the mine was evaluated.It was found that the main geological disasters in the study area were ground subsidence and ground fissures.Mining activities did not damage the aquifer or have less impact on the aquifer,but had a greater impact on the original terrain and geomorphic landscape.The damaged degree of land resources was serious.Based on this,the comprehensive management technology of mine geological environment was proposed,including site leveling technology,road technology,drainage channel technology,greening technology,soil fertilization and tillage,management and protection technology,etc.The research can avoid or reduce the impact and damage of mining activities on the mine geological environment to the maximum extent,and realize the effective recovery of the mine geological environment.
