TDR测定井筒中心坐标的新工艺

TDR New Technology Used for Measuring the Coordinales of Mine-shaft Center

介绍了测定井筒中心坐标的一种新方法(TDR),即应用全站仪和双微棱镜测杆,测定待延深井简井壁上若干点的坐标,运用最小二乘拟合方法排算井筒中心坐标.通过传统的测定井筒中心坐标方法进行比较,证明这种方法能够提高测量工作效率,满足井筒延深时的精度要求.

A new method, total-station and double mini-prism surveying rod,used for measuring the coordinates of mine-shaft center has been introduced in the paper. A total station and a double-prism surveying rod are used to measure the coordinates of several points on the mine-shaft wall.Then the least-sguares regression has been applied to calculate the coordinates of the mine-shaft center. Through the comparision between the new method and the traditional method,it is proved that the new method can improve the work efficiency and fulfil the precision requirement of mine-shafting.
