结合酒钢镜铁山矿桦树沟井下铜矿采切工程上向天井掘凿过程中各开采分层定向的实际应用,介绍全站仪单三角形后方交会法的原理,并对单三角形后方交会的计算方法进行分析与尝试,推导计算公式,得出其工作效率及精度方面都是可取的,且通过实践证明其是可行的。
Combined with the practical application of stratified orientation in the process of digging to the pits during the cutting and cutting project of the Bingshugou underground copper mine in Jing Tieshan Iron Mine, the principle of total station single triangle trailing intersection method is introduced, and the single triangular rear intersection The calculation method is analyzed and tried, the calculation formula is deduced, and the conclusion is that it is feasible in terms of work efficiency and accuracy, and it is proved to be feasible through practice.
