摘要
以攀枝花市某煤矿中小型矸石堆场为研究对象,提出了 一种集坡面生态防护、集水装置、土壤改良和植被配置为一体的适用于中小型矸石堆场边坡植被的免覆土快速恢复技术.通过坡面治理技术、土壤改良技术和植物修复技术,制定修复方案,以改善边坡的立地条件,降低矸石堆场对生态环境的影响.研究表明,该方法实施150 d后,研究区植被覆盖度达95％以上,植物存活率达到95％以上,水土流失率减少了 85％以上,显著提高了矸石堆场边坡植被的恢复效果,降低了矸石堆场对周边生态环境的影响.该研究为中小型煤矸石堆场免覆土生态修复提供了一种有效的技术手段,有望推动矸石堆场的生态重建及矿区环境的良性发展.
Abstract
This study is focused on the mid and small-scale coal gangue heap in a coal mine in Panzhihua City.Rapid restoration technology of slope vegetation without covering soil is proposed,which integrates slope ecological protection,water collection facilities,soil improvement,and vegetation configuration.By u-sing slope treatment technology,soil improvement technology,and plant restoration technology,a restora-tion plan is developed to improve the vertical environmental conditions of the slope and to reduce the im-pact of the gangue heap on the ecological environment.The results show that after 150 days of the applica-tion of the method in the study area,the vegetation coverage has reached more than 95％,the survival rate of plants has reached more than 95％,and the soil erosion rate has been reduced by more than 85％,which significantly improves the restoration effect of the slope vegetation of gangue heap and reduces the impact of the gangue heap on the surrounding ecological environment.This study provides an effective technical means for the ecological restoration of small and medium-sized coal gangue piles without cover-ing soil,which is expected to promote the ecological reconstruction of gangue heap and the benign devel-opment of mine environment.
