迁安市露天开采矿山地质环境综合治理关键技术研究

Research on key technology of comprehensive treatment of geologicalenvironment of open-pit mines in Qian′an City

迁安地区的露天矿山为满足市场需要,高强度、大范围地对矿山进行开发,由于其在开采过程中忽视了对生态环境的恢复治理和保护,导致矿山原有的环境遭受了巨大的破坏,甚至由于露天开采矿山而引发的次生地质灾害也在逐渐增加,寻找出高效的治理措施已刻不容缓。系统分析了当前迁安市露天开采矿山地质环境综合治理的关键技术的优缺点,收集了排土场种植沙棘、缓坡鱼鳞坑栽植灌木、陡坡采用植生袋等新兴技术,绿化植被本土化,引入社会资本等效果较好的治理措施。通过治理可最大限度地减轻矿业活动对矿山地质环境及土地资源的影响和破坏,促进绿色矿山建设、生态文明建设和矿区经济可持续发展。

In order to meet the needs of the market,the open-pit mines in Qian′an area develop the mines with high intensity and on a large scale,because they ignore the restoration and protection of the ecological environment in the mining process,resulting in huge damage to the original environment of the mine,and even the secondary geological disasters caused by the open-pit mining are gradually increasing.It′s urgent to find efficient governance measures.In this paper,the advantages and disadvantages of the key technologies for the comprehensive improvement of the geological environment of the open-pit mining mines in Qian′an City are systematically analyzed,and the emerging technologies such as planting sea buckthorn in the drainage field,planting shrubs in the fish scale pit on the gentle slope,and using plant bags on the steep slopes,the localization of green vegetation,and the introduction of social capital are collected.Minimize the impact and damage of mining activities on the geological environment and land resources of mines,and promote the construction of green mines,the construction of ecological civilization and the sustainable development of mining areas.
