摘要
随着金川矿山开采深度的加大和掘进工艺的提高,传统的水准测量及三角高程测量方式已不能满足矿区生产的要求。为了解决上述问题,本文通过对全站仪三角高程测量原理进行分析,推导了中间法三角高程的误差传播公式,并结合金川矿区工程实际验证。结果表明:全站仪中间法三角高程测量的精度可以达到金川矿区Ⅱ级水准测量精度要求,在一定范围内可以达到金川矿区Ⅰ级水准测量精度要求。随着测量仪器精度的不断提高,该方法也将会在未来矿区工程中得到广泛应用。
With the increase of mining depth and the improvement of advancing technology in the Jinchuan Mine,the traditional leveling and trigonometric leveling methods can no longer meet the requirements of mining production.In order to solve the above problem,the principle of the total station trigonometric leveling using midway method is analyzed in this paper and the error propagation formula of the intermediate trigonometric leveling is deduced and verified against the engineering realities in the Jinchuan Mine area.The results show that the accuracy of the total station trigonometric leveling using midway method can meet the Class II leveling accuracy in the Jinchuan Mine,even Class I accuracy of the mine to a certain extent.With the continuous improvement of the measuring instrument accuracy,this method will also be widely applied in future mining engineering works.
