| 摘 要： | 针对复杂地表条件下采用水准测量和导线测量等常规方式进行地表变形周期观测、任务量大甚至无法实施等问题,提出了建立研究区域的似大地水准面精化模型,同时采用GPS-RTK技术获取观测站三维空间信息,进而获得概率积分法预计参数。最后以内蒙古准格尔旗某煤矿的生产实践说明该技术的有效性和可行性,极大地提高了工作效率,为保护煤柱的留设提供了科学的依据。

| Abstract: | Owing to the variability of mine surface,it is difficult to obtain the deformation monitoring data of observation stations by traditional leveling technique.Hence,we proposed to establish regional quasi-geoid refinement model.On this basis,GPS-RTK technique was employed to obtain 3D spatial information of observation stations in an Inner Mongolia coal mine,by which,calculating predicted parameters using probability integral method.Meanwhile,the results show that the technique is valid and feasible,and can fast acquire the mining subsidence information,which can provide scientific basis to reserve protective coal pillar. |
