摘要
在矿山测量工作中,巷道掘进以及贯通都需要进行矿山井下的导线测量,而目前的测量方法为全站仪的测量方法,但目前使用全站仪对于矿山巷道导线测量偏差较大,提高矿山巷道导线测量精度的方法研究,对于平面控制测量工作中产生的横向贯通中误差通过计算误差等级来改善测量路线,对于高程控制测量工作中的竖向贯通中误差,改善测量模式以及测量方法,并且采用偏心测量仪来降低在测量中偏心差对于精度的影响。通过实验分析,改善方法有效,具有可行性。
In the mine survey work,the traverse survey in the mine shaft is needed in the tunnel excavation and through,and the current survey method is the total station survey method,but at present,the total station is used for the traverse survey deviation in the mine tunnel,the method research of improving the traverse survey accuracy in the mine tunnel,and the horizontal through error in the plane control survey work is passed The error grade is calculated to improve the survey route.For the vertical through error in elevation control survey,the survey mode and method are improved,and the eccentricity meter is used to reduce the impact of eccentricity on the accuracy.Through experimental analysis,the improvement method is effective and feasible.
