Research on measurement technique of long borehole trajectory in mine shaft

In view of the problem of long borehole trajectory measurement in coal mine，two long drilling trajectory measurement methods were adopted，which can be used to measure and record the inclination angle and azimuth angle of the horizontal drilling or directional drilling without cable，and the drilling trajectory data including the minimum curvature method and the mean angle total distance method were carried out.The study of the calculation method has carried on the research of the common error causes and correction errors in the borehole trajectory measurement.Through the measured borehole trajectory data，the data analysis method and the effect of the borehole trajectory measurement were analyzed.Through the theoretical and measured data，it was considered that the drilling trajectory measurement technology and the error correction method were proposed.Higher drilling trajectory measurement accuracy，can be used to mine borehole trajectory measurement.
