摘　　要：为监测地下煤炭开采对某矿工业广场内主、副井筒的影响,布设了由54个监测点和2个基准点组成的监测网。监测网的基准时段测量采用静态GPS相对定位技术和三等几何水准,以此作为沉降监测基础;监测时段外业观测方法与基准时段的相同,但沉降量采用以似单差法为理论的GQuickS软件进行解算,并与几何水准测得的沉降量进行比对分析,结果表明,采用似单差法进行沉降监测可达到三等水准监测的要求。In order to monitor the deformation of the main and auxiliary wells in a mine industry square caused by underground coal mining, a monitoring network composed of 54 monitoring points and two datum points is established. The global positioning system（GPS） static relative positioning method and three-degree geometric leveling are adopted for the datum session measuring of the monitoring network, and the measuring results are used as subsidence monitoring datum. The observation meth- od of monitoring session is the same as that of datum session, but the subsidence values are computed by GQuickS software based on the similar single-difference methodology（SSDM）, and compared with that of geometric leveling. The results show that the SSDM based subsidence monitoring can be up to the monitoring requirement of three-degree leveling.
