Abstract:

Aiming to solve the problem of inclined roadway waistline Calibration，more effective and accurate methods are provided based on the available knowledge and practice.The author has tried the methods of waistline correction and quadratic Pseudo-dips and has analyzed their accuracy.Progress has been made in theory and research methods as regards the two approaches.It not only perfects the theory of setting-out inclined roadway waistline to some extent but also completes this research method.The results show that during mining，both of the two time-saving methods can reach the accuracy level and they can solve problems more easily and effectively.

Key words: Inclined roadway, Waistline correction, Quadratic pseudo angle, Correction
