摘要
一井定向是竖井平面联系测量的一种主要方式。本文结合具体工程实例,在分析一井定向原理的基础上,给出了一井定向的作业步骤,总结了一井定向数据的平差计算方法,并设计了具体的计算表格,最后总结了一井定向在实际生产中能够提高定向精度的几点经验。
Single shaft orientation is a main method of vertical shaft plane contact measurement. Combined with specific engineering example,this paper on the basis of analyzing the principle of single shaft orientation,gave out the operation steps of single shaft orientation,and summarized single shaft orientation data adjustment calculation method,and brought out the concrete calculation form,finally summarized some experience that in practical production can improve the accuracy of single shaft orientation.
