两井贯通测量的方法研究

Research on the Method of Through Two-well Measurement

以寺河矿常店进、回风立井与井下东六盘区大巷贯通为例,通过对测量方案及其允许误差确定,在地面采用D级DPS控制测量,井下采用全站仪导线测量和陀螺全站仪定向测量,减收了工作量,缩短了工作时间,大大提高了两井贯通的精度,为今后的大型贯通提供可靠的技术参考。

Taking the return air shaft and the main roadway of Dongliupan underground as an example,through the determination of the measurement scheme and its allowable error,the D grade DPS control survey is adopted on the ground.The downhole use of total station traverse survey and gyroscope total station orientation survey reduces the workload,shortens the working time,greatly improves the precision of the two wells through,and provides a reliable technical reference for the large-scale penetration in the future.
