一种高效率井下导线测量辅助系统

The high efficiency auxiliary system of underground traverse survey

针对在煤矿井下导线和陀螺定向测量中,采用点下仪器对中操作过程往往耗时长且易造成明显的对中误差,并严重影响了矿井测量工作的效率和精度的问题,该文提出一种无需仪器精确对中的改进方法。通过安置一套测定对中偏差的触屏读数装置及内置数据处理系统,对观测数据进行自动偏心改正,较好地消减了井下导线测量或陀螺定向的对中误差影响。

Aiming at the problem that using under the point instrument centering usually consumes long time and generates significant errors in the underground traverse and gyro-orientation survey of coal mine, which seriously affects the efficiency and precision of mine surveying work. For this reason, an im- proved method was proposed, which did not need to be accurately instrument centering. By placing a touch screen reading device and a built-in data processing system of measuring center errors, which could auto- matically eccentricity correction for observation data. Meanwhile, this system could reduce the influence of underground traverse survey or gyro orientation.
