中文摘要:

为揭示贵州北部煤炭矿区地下开采引发的地表形变规律，本文以习水县煤矿集中开采区为研究区，基于2019年6月至2024年11月共13期ALOS-2升轨数据，采用SBAS-InSAR技术提取研究区地表形变时空演变特征，结合矿权信息与实地调查验证，结果显示:监测期内共识别出13处重点地表形变区，其年平均形变速率变化范围在-363595201932 mm/a；地表形变时空变化特征与矿山地下开采活动密切相关，有11处形变区位于采矿范围内，在矿山开采前地表稳定，随着地下开采及时间延续，发生了持续性和连贯性的地表形变，其范围和程度不断增加，最大累计形变量达到-2 145 mm。研究表明:采用SBAS-InSAR技术和ALOS-2影像能有效监测出煤炭矿区地表形变，监测结果可靠且与实际煤矿开采活动具有一致性，可为矿区地质灾害早期识别、矿山安全生产的监测预警提供参考。

英文摘要:

In order to reveal the surface deformation caused by underground mining activities in the coal mining areas of northern Guizhou，it selected the Xishui County coal mine intensive mining area as the research zone in this studyBased on 13 ascending orbit ALOS-2 datasets from June 2019 to November 2024，the SBAS-InSAR technique was employed to obtain extract spatiotemporal characteristics of surface deformation，combined with validation through mining rights information and field investigations，revealed the following results:Thirteen key surface deformation zones were identified during the monitoring period，with annual average deformation rates ranging from -363595 to 201932 mm/aThe spatiotemporal characteristics of surface deformation showed strong correlations with underground mining activities，with 11 deformation zones located within active mining areasThese areas exhibited stable surfaces prior to mining operations，but developed continuous and coherent deformation patterns as underground extraction progressed over time，with both the spatial extent and deformation magnitude increasing steadilyThe maximum cumulative deformation reached -2 145 mmThe study demonstrates that SBAS-InSAR technology combined with ALOS-2 imagery can effectively monitor surface deformation in coal mining regions，yielding reliable results consistent with actual mining activitiesThis approach provides valuable references for early identification of geological hazards and monitoring warnings for mining safety in coal mining areas
