摘　　要：为解决煤矿井筒十字中线点标定的高精度测量难题,介绍一种极坐标归化法,研究其测量原理、技术路线与实现方法。在采用GNSS静态测量构建近井控制网、RTK测量粗略标定十字中线点的基础上,首先采用极坐标法设置过渡点,然后通过精密测量,计算过渡点位置与设计位置的偏差,并据此进行归化改正,直至满足技术规范要求。基于Excel编制数据记录计算表格,实现中线标定的无纸化作业以及归化改正量的即测即得,提高工作效率。工程实践表明:该方法操作方便,测量成果可靠,通过1~2次归化改正即可满足技术规范要求,且作业效率比常规方法提高一倍。In order to solve the difficult problem of high precision setting-out of mine cross middle line points in coal mine shaft,a polar coordinate reduction method is introduced,and its measuring principle,technical route and realization method are studied.On the basis of GNSS static survey to construct near-well control network and RTK survey to roughly setting-out mine cross middle line point,the temporary point is set by polar coordinate method at first,and then the deviation between the temporary point and the design position is calculated by precise measurement,and the deviation is corrected accordingly until the technical specification is satisfied.Based on Excel,the paperless operation and real time calculation of reduction correction are realized,and the work efficiency is improved.The engineering practice shows that the method is easy to operate and the measurement results are reliable.The technical specifications can be met by 1~2 reduction corrections,and the operation efficiency is twice as high as the conventional method.
