摘要
结合阳煤集团二矿470水平15号煤十采区轨道巷与二矿龙门立井贯通的实例,通过导线平差各项参数的选择,从加测陀螺定向边和不加测陀螺定向边两方面对贯通精度的影响做出了分析比较,指出在相同的观测方法和条件下,合理加测陀螺定向边能大大提高贯通精度。
Combining with the pass-through practice of Yangmei group No. 2 470 horizontal 15 coal-mining rail transit and mine No. 2 Longmen well as an example,through selecting leading line error parameters,analyzes the impact of geo-orientation with measurement and without meas-urement upon pass-through accuracy,and points out that：rationally measuring gyro-orientation can greatly improve pass-through accuracy under same detection methods and conditions.
