航空摄影测量技术在山西平朔煤矿区大比例尺地形图测量中的应用

Application of aerial photogrammetry in large scale topographic map survey in Pingshuo coal mine area,Shanxi Province

针对山西平朔煤矿区矿山地形图陈旧无法满足现阶段矿山生态恢复治理,地质防治等领域的应用需求,应用航空摄影测量技术对煤矿区进行大比例尺地形图测绘。结果表明:航空摄影测量技术在矿山大比例尺地形图测绘中具有良好的应用效果,不仅减少了大量的外业工作量,降低了测绘成本,而且所获地形图精度较高;航空影像数据在后期地形图制作方面操作简便,提高了地形图制作效率,同时为地形图的缩编等提供了便利,间接提高了地形图的综合利用率。

Considering that the outdated mine topographic map of Pingshuo coal mine area in Shanxi Province cannot meet the application requirements in the fields of ecological restoration and geological control at the present stage,large scale topographic mapping of the coal mine area was drawn by aerial photogrammetry.The results showed that the aerial photogrammetry hadgood application effects in surveying and mapping of large scale mine topographic map.It reduced a large amount of field work andcost,but also obtainedtopographic maps in high precision.At the same time,aerial image data is easy to edit in the post production of topographic map,which improved the production efficiency of topographic map,and provided convenience for the reduction of topographic map.The technique indirectly improved the social service benefits of topographic map.
