The present invention provides a full-roadway full-process full-cross-section
deformation monitoring device and a monitoring method thereof, which are applicable to the field of roadway
surface deformation monitoring. A monitoring
station is deployed utilizing an anchor
rope, a supporting frame and a rotary
laser measuring device are connected via a threaded sleeve at the
tail end of the anchor
rope, the rotary
laser measuring device can rotate and drive a
laser range finder to rotate, the data of a plurality of cross sections can be measured at the same time with one monitoring
station, the data is processed by
computer programming, so that the measurement data is converted into coordinates in a three-dimensional coordinate
system, and thereby full-roadway full-process full-cross-section
digital imaging is realized. The monitoring method attains high measuring accuracy, involves very low artificial error, supports intuitive observation of dynamic roadway deformation condition, can provide accurate warning for roof pressure condition, and provides a technical guarantee for safety of the downhole workers.
