摘要/Abstract

摘要： 矿区地表形变的高效监测对灾害防控和生态保护至关重要。本文以东胜煤田露天矿与井工矿为研究对象,基于陆探一号(LT-1)L波段SAR卫星数据,结合D-InSAR和InSAR技术,实现了矿区地表沉降监测与数字高程模型(DEM)反演,并通过实测高程与无人机数据验证其精度。结果表明:①LT-1数据可有效捕捉大梯度形变(>1 m),露天矿沉降范围广(最大39 cm),井工矿沉降深度大(最大135 cm),且形变点随采掘方向动态迁移;②无控点条件下,LT-1 DEM与无人机DEM的高程差异93%集中在5 m内,满足1∶50 000制图标准;③双星编队模式显著提升了监测效率,4 d重访周期可支持矿区形变动态追踪。LT-1数据在复杂矿区形变监测与高精度地形重建中具有优势,为矿山安全与生态修复提供了可靠的技术手段。

Abstract: Efficient monitoring of surface deformation in mining areas is vital for disaster prevention and control and ecological protection.This paper takes the open-pit mine and underground mine of Dongsheng coalfield as the research object.Based on the L-band SAR satellite data of LT-1,combined with D-InSAR and InSAR technologies,the monitoring of surface subsidence in the mining area and the inversion of DEM are achieved,and the accuracy is verified through the measured elevation and unmanned aerial vehicle data.The results show that: ①The LT-1 data can effectively capture large gradient deformations (>1 m),the subsidence range of open-pit mines is wide (up to 39 cm),the settlement depth of underground mines is large (up to 135 cm),and the deformation points migrate dynamically along with the mining and excavation directions.②Under the condition of no control points,93% of the elevation difference between LT-1 DEM and unmanned aerial vehicle DEM is concentrated within ±5 m,meeting the mapping standard of 1∶50 000.③The dual-star formation mode significantly enhances the monitoring efficiency,and the 4 d revisit cycle can support dynamic deformation tracking in the mining area.This study confirms the advantages of LT-1 data in deformation monitoring and high-precision terrain reconstruction in complex mining areas,providing reliable technical means for mine safety and ecological restoration.
