| Abstract: |
| 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. |
