摘　　要：针对地下盐矿开采必然会引起地面沉降问题,本文基于广州市龙归硝盐矿矿区28年连续的精密水准测量和位移监测数据,分析了该矿区沉降情况,阐述了沉降时间和空间特征,推断了引发沉降的原因,可为指导矿区及其周边受影响区域的地质灾害预警和防治工作提供参考。Focusing on the problem of land subsidence inevitably caused by underground salt mining,Based on the 28 years of uninterrupted precision leveling and displacement monitoring data in Longgui nitratine-ores area,this paper analyzes the subsidence situation of the mining area,describes the temporal and spatial characteristics,and inference the causes of the subsidence,which can provide references for timely guidance of the early warning and prevention of geological disasters in the mining area and its surrounding affected areas.
