Description
technical field [0001] The invention relates to a laser measuring device for surface deformation of the surrounding rock of an underground roadway, in particular to a deformation measurement of the surrounding rock of a mining roadway which is suitable for accurate measurement of the deformation of the surrounding rock of the roadway, data storage, image display and data exchange. device. Background technique [0002] With the increase of mine mining intensity and scope, the cross section of the roadway is continuously enlarged, and the accidents of roof caving are increasing, which not only poses a direct threat to the personnel and equipment of the roadway construction, but also affects the construction progress. Therefore, it is of great significance to grasp the deformation of the roadway surrounding rock in time for the formulation and implementation of coal mine production plan. At present, the monitoring of the tunneling progress of coal mines is mainly done manually...
