摘要
随着会泽铅锌矿深部大规模储量的发现,为深部采矿服务的测量工作需及时展开。对于导线点数较多、长短边悬殊较大、观测精度不相同的附合导线如何进行平差计算,是一个十分重要的课题。本文采用导向联系三角形观测方法,导出了矿井定向角度的误差计算公式。对于多达60个待定点、总长达5713.433m的附合导线,采用不等精度导线平差方法,最大点的误差仅6.85cm,而长短边悬殊处达170倍,说明采用的观测方法正确,整条导线的点位是稳定的。
Being discovered large quantity of additional reserves in deeper section of Huize lead and zinc mine, some survey needs to be carried out so as to help the mine to start its mining work in time. But the calculation of error compensation made the survey a hard job owing to the survey being in such a complicated situations, as being of complex leads with many lead points,great difference between the long and short sides, and different observation precision. This paper educed the error calculation formula of the mine directional angle by using the method of guidance relation connected with the triangle observation. With the use of this formula in the case of the complex leads, with 60 points, with a total length of 5713.433 meters, the biggest point error was only 6.85cm,while the difference between the long and short side reached 170 times. The result confirmed that the adopted observation method is correct, and the entire lead localization is stable.
