technical field [0001] The invention relates to the technical field of roadway deformation measurement, in particular to a three-way intelligent laser roadway deformation monitoring device and method. Background technique [0002] At present, most coal mines use manual methods to measure the roadway deformation, make markings in advance, and regularly measure the distance between two markers with a tape measure to provide basic data for analyzing the movement law of surrounding rocks. , low precision and other shortcomings. There are also mechanical and electronic instruments, such as hand-held measuring instruments. Workers enter the roadway to hold the instrument to measure, and store the data in the instrument. The hand-held collector is used to collect data manually at regular intervals, and the data is sorted and analyzed after entering the computer in the well. Similarly There are shortcomings such as the inability to guarantee the orthogonal plane and the large maint...
