巷道中心偏差的快速计算及快速校正

Quick calculation and rapid correction of tunnel center deviation

在矿井生产测量工作中,常常需要现场进行数据计算。由于生产与测量工作互相影响、掘进工作面设备与物料较多等原因,导致新测点与中心点不通视,造成测量工作难度大、时间长、效率低、对生产影响大等问题。针对这些问题,对现场计算偏差的方法和施测方法进行了改进优化,实践证明这一方法能有效地解决上述问题。

In mine production surveying,data calculation is often needed at the scene. Due to the mutual influence of pro- duction and measurement, and the large number of equipment and materials in tunneling face, the new measuring point and the central point are not visible, resulting in large difficulty, long time and low efficiency of measurement work. Aiming at these problems, the calculating deviation method and the measuring method were improved and optimized. The practice proves that the methods can effectively solve the above problems.
