摘　　要：为解决卓尼县历史遗留的小型采石场较多且地质环境问题突出等问题,通过对卓尼县业日村某采石场勘查分析,矿山现状条件下存在的主要矿山地质环境问题为不稳定边坡、崩塌、滑坡地质灾害隐患、地形地貌景观破坏等。针对渣堆不稳定边坡采用坡脚修建挡墙、坡体分级削坡减载的治理措施,及客土后“乔灌草”混种的复绿措施;针对岩质边坡存在的崩塌落石采用危岩清理的治理措施,及“生态棒+客土喷播”的复绿措施;针对土质边坡滑坡采用降低边坡坡度、压脚护岸、设置截排水沟的治理措施,最终达到消除地质灾害隐患、提升植被覆盖度、修复山体地形地貌景观的目的;对甘南地区同类型小型采石场生态修复具有一定的参考价值。There are many historical stone quarries in Zhuoni County,and the geological environ⁃ment problems are prominent.Through the exploration and evaluation of Yeri Village quarry in Zhuoni County,it is concluded that the main geological environment problems of the mine under the current condi⁃tions are unstable slopes,collapses,landslide geological hazards,landscape damage,and land resource damage.In view of the unstable slope of slag heap,the treatment measures of building retaining wall at the foot of the slope,grading slope cutting and load reduction,and the regreening measures of"arbor,shrub and grass"mixed planting after the guest soil are adopted.The treatment measures of dangerous rock clean⁃ing and regreening measures of"ecological rod+earth spraying"are adopted for the collapse rock existing in rock slope;in view of the soil slope landslide,the control measures of reducing slope gradient,foot re⁃vetment and setting up drainage ditch are adopted to eliminate the hidden dangers of geological disasters,improve the coverage of vegetation and repair the landscape of mountain topography.It has important refer⁃ence significance for ecological restoration of similar small quarries in Gannan Prefecture.
