Abstract
A new method of improved double baseline steel wire method was used to monitor the shaft deformation in the auxiliary shaft of Niuerzhuang Mine in Fengfeng Mining Area. Based on the two steel wires point P1 and P2, the eight directions from Q1 to Q8 were determined by using the designed directional ruler coincide with the two points, and the distance from P1 to the shaft wall Q1 to Q8 was measured by laser rangefinder, so as to fit the cross section of the shaft. The deformation of the shaft is monitored by fitting the center point of the section and the change of radius. Compared with the traditional four-datum vertical line method, it is easier to measure, shorter in monitoring time and more efficient on the premise of ensuring accuracy.
