摘要
在磁性矿区中用于矿区孔内顶角无缆自动记录测量最主要的仪器就是STL-1GW型无线存储式数字陀螺测斜仪,针对这一应用现状,提出STL-1GW型无线存储式数字陀螺测斜仪在磁性矿区中的应用与探讨。通过STL-1GW型无线存储式数字陀螺测斜仪进行磁性矿区地面定向,以经纬仪测量出仪器所处的方位即为仪器定向方位角;通过磁性矿区下孔测量,计算下孔测量方位角误差,减少磁测状态下下孔测量的误差;利用ARM进行钻孔深度的记录,通过无线存储式芯片内部的高速信息处理器计算钻探的倾斜角度、面向角参数等,同时提取对3~5个有效点,实现磁性矿区内顶角无缆自动记录。
Stl-1gw wireless storage digital gyroscope inclinometer is the most important instrument for automatic recording and measuring the top angle of borehole in magnetic mining area.In view of this application status,the application and discussion of stl-1gw wireless storage digital gyro inclinometer in magnetic mining area is proposed.Through stl-1gw wireless storage digital gyroscope inclinometer for magnetic mine ground orientation,the azimuth measured by theodolite is the instrument orientation azimuth angle;through the magnetic mining area down hole measurement,calculate the down hole measurement azimuth error,reduce the magnetic measurement error;use arm to record the drilling depth,through the wireless storage chip internal height At the same time,3~5 effective points are extracted to realize the automatic recording of the top angle without cable in the magnetic mining area.
