摘　　要：菏泽市郓城县作为新兴的煤炭城市,是国家重要的能源基地,伴随煤炭资源开采而来的各种地质环境问题,给当地群众生产生活以及经济社会发展带来不利的影响。本文基于高精度水准测量、GPS测量和合成孔径雷达干涉测量技术获取郓城县近1000 km 2范围监测区煤矿开采区域2016年沉降监测数据,同时利用同时期机载LiDAR点云和山东省“十一五”1∶10000基础测绘高程点成果生成沉降等值线图,两者对比发现沉降范围和沉降结果吻合较好,监测区最大沉降量达100 mm。Yuncheng County of Heze City is a new coal city and an important energy base of the country.All kinds of geological environmental problems with the exploitation of coal resources have a negative effect on the production and life of the local people as well as the economic and social development.In this paper,obtained the subsidence monitoring data for the year 2016 of Yuncheng County nearly 1000 square kilometres coal mining monitoring region based on the fusion technique of high precision levelling,GPS measurement and synthetic aperture radar interferometry.Meanwhile,with the same period of airborne LiDAR point cloud and Shandong province“11th Five-Year”1∶10000 basic mapping elevation point generated settlement contour map,it coincided with the settlement range and the settlement result,the maximum settlement of the monitoring region is 100 mm.
