Abstract

In consideration of the disadvantages of the traditional contact-type measure methods for deformation measurement in large section roadway, the in-situ measure method and tool is developed with the theory of laser-based distance measuring. The novel multi degree of bracket set makes a stable connection between the primary measure points and portable laser rangefinder, which makes sure that the new device's position still kept in the same initial state after measure. Therefore, the accuracy and reliability of deformation measurement have been improved a lot so that having realized in-situ measurement. Then, a set of measure method have been created based on the new device and the improved cross arrangement method for measure points, which have been used in the long-term deformation monitoring task in large cross section roadway in Maluping mine area, and its noted data has revealed the deformation mechanism and ground pressure manifestation law in the deep roadways of soft rock under high-stress state, which providing the primary information as theoretical foundation for support design.
