摘要
地面塌陷是地下矿产采空区常见的一种地质灾害,由矿山开采引起的地面塌陷往往形成洼地、槽谷或负地形,并伴随有不规则的开裂和地形起伏,对人类生产活动造成极大的危害。本文以陕西某矿区为例,根据其2011年高精度地形图数据和2021年高精度地形图数据,提取其高程点、等高线数据,在ArcGIS平台下生成高精度DEM数据,对比两期DEM数据,分析得出塌陷区域,并且套和其采掘平面工程图进行验证,为更合理地规划人类生产生活活动以及防治自然灾害提供强有力的支撑。
Ground collapse is a common geological disaster in underground coal mine goaf.The ground collapse caused by mining often forms depressions,troughs or negative terrains,accompanied by irregular cracking and topographic fluctuation,which causes great harm to human production activities.Taking a mining area in Shaanxi as an example,according to its high-accuracy topographic map data in 2011 and 2021,this paper extracts its elevation point and contour data,generates high-accuracy DEM data under ArcGIS platform,compares the two phases of DEM data,analyzes the collapse area,and verifies it with its mining plan engineering map,so as to provide strong support for more reasonable planning of human production and living activities and prevention and control of natural disasters.
