摘　　要：为解决煤田开采地表变形监测传统测量方法全人工作业、工作效率低等问题,针对煤田开采地表变形监测布网特点,设计了VRS技术用于监测煤矿地表变形的施测方案。数据表明,大地高高差的测量精度能达到中误差为±3.2 mm/km,满足四等水准测量的精度要求,点位平面坐标内部精度为mm级,符合《煤矿测量规范》的精度要求。In order to solve problems of total manual operating and low efficiency of conventional method,this paper put forward a new method monitoring surface deformation based on VRS technology,according to establishment characteristics of deformation monitoring network.The test results show that precision of geodetic height difference reaches ±3.2mm,which can satisfy the demand of fourth-grade-levelling,and internally coincident of plane coordinate also reaches millimetre level,which can satisfy the precision demand made by mining surveying specification.
