    Monitoring and Analysis of Mine Geological Disasters of Liao Yuan Coal Mine in Hancheng City Based on Remote Sensing Technology

    • 摘要: 以获取的韩城市龙门镇燎原煤矿2013、2018、2022年等3个年度的卫星影像作为主要数据源,并辅以矿区范围内30m的ALOS高程数据,通过对影像和高程数据进行处理,根据影像特征建立了研究区矿山地质灾害遥感解译标志,利用ArcGIS平台重点解译了采空区范围内出现的地裂缝、地面塌陷、落水洞及沟谷边缘疑似出现的滑坡、崩塌等地质灾害。结果表明:(1)研究区地质灾害数量偏高,共解译滑坡、崩塌、地面塌陷、地裂缝灾害点总计42处;(2)研究区地质灾害发生与人类工程活动(采矿活动)、区内地形条件、地质背景、物候条件密切相关;且灾害点大多形成于2013年之后,主要发生在坡度15°-30°和30°-45°之间。

       

      Abstract: In this study,the primary source of data was satellite images of the Liaoyuan Coal Mine in Longmen Town,Hancheng City,collected over a period of three years(2013,2018,and 2022).To supplement this data,30 m ALOS elevation data from within the mining area were also utilized.By analyzing these data,a remote sensing interpretation system for mining geological disasters in the study area was established based on image characteristics.The ArcGIS platform was employed to interpret geological disasters,including geocracks,ground collapses,sinkholes,landslides,and avalanches suspected to occur along the edge of the gully within the scope of the mining area.The results revealed the following:first,the number of geohazards in the study area was considerable,with a total of 42 landslides,ground collapses,and ground cracks;second,the occurrence of geohazards in the study area was closely linked to human engineering activities(mining activities),topographical conditions of the area,geological background,and climatic conditions.The majority of the hazards were formed after 2013 and primarily occurred on slopes with angles between 15° and 30°,as well as between 30° and 45°.
