| 中文摘要: |
| 易门县铜矿开采为当地经济发展起到了极大的推动作用，随着资源的不断采掘，采空区的数量和规模不断扩大，造成山体稳定性降低，极易诱发以地面塌陷为主的地质灾害，对人类生命财产安全及地区生态环境形成较大的威胁。本文联合 InSAR、无人机遥感技术结合地面详细调查弥补了传统技术手段的不足，对易门县铜矿采空区地面塌陷快速、有效地开展了监测工作，查明了其发育情况及特征，科学合理地开展了分区及风险性评价工作。结果表明，研究区可划分凤山地面塌陷区、狮山地面塌陷区、明塘地面塌陷区 3个分区，通过对其活动性、危害性进行定性评价，凤山地面塌陷区、狮山地面塌陷区判定为高风险等级，明塘地面塌陷区判定为中风险等级。 |

| Copper mining in Yimen County has played a significant role in promoting the local economic devel-opment. With the continuous extraction of resources, the number and scale of mined-out areas have been continu-ously expanding, resulting in a decrease in the stability of the mountain and making it highly prone to geological di-sasters mainly characterized by ground subsidence, posing a considerable threat to human life and property safety as well as the regional ecological environment. This paper, by integrating InSAR and unmanned aerial vehicle (UAV)remote sensing technologies with detailed ground investigations, has made up for the deficiencies of traditional tech-nical means. It has rapidly and effectively carried out monitoring work on ground subsidence in copper mine goaf ar-eas in Yimen County, clarified its development and characteristics, and scientifically and reasonably conducted zon-ing and risk assessment work. The results show that the study area can be divided into three zones: Fengshan groundsubsidence zone, Shishan ground subsidence zone and Mingtang ground subsidence zone. Through qualitative evalu-ation of their activity and hazard, the Fengshan ground subsidence zone and Shishan ground subsidence zone areclassified as high-risk areas, while the Mingtang ground subsidence zone is classified as medium-risk areas. |
