The invention relates to a system for acquiring a roof crack expansion image of a coal mine roadway and an acquisition method thereof. The system comprises a high-definition camera capable of continuously monitoring the development process of roof cracks of the roadway, a high-strength transparent protective pipe, an anchoring section, a fixed section and sectional connecting rod, wherein the front end of the high-strength transparent protective pipe is fixedly connected with the anchoring section, the rear end of the high-strength transparent protective pipe is in threaded connection with the fixed section, and the anchoring section is fixed at the bottom of a borehole by using an anchoring agent to achieve the fixation of the high-strength transparent protective pipe in the borehole; and the high-definition camera is flexibly connected with the sectional connecting rod, can move along the high-strength transparent protective pipe under the action of the sectional connecting rod, or can be firmly arranged in the sectional connecting rod to monitor the development process of the cracks, and during the process, the fixed section is connected with the high-strength transparent protective pipe to block the pipe body. According to the system and the acquisition method thereof disclosed by the invention, the equipment can be matched with a roadway surrounding rock introscope to perform dynamic image acquisition for the specific cracks of the roof integrally and long-timely during use, and the problem that the reliable data acquisition of dynamic expansion of the roof cracks cannot be implemented in practical engineering can be overcome.
Description
technical field [0001] The invention relates to the field of mine roadway engineering tools, in particular to a coal mine roadway roof fissure expansion image acquisition system capable of continuously collecting data on the roof crack dynamic expansion image and a collection method thereof. Background technique [0002] The roof of the roadway is a general term for the top of the surrounding rock of the roadway. The roof of the mining roadway, as the coal and rock mass encountered in the excavation, is a complex geological body that exists in a certain geological environment. One of its characteristics is that the coal and rock body contains various cracks such as joints and beddings, which makes the coal and rock mass become unsightly. continuum. Cracks will expand due to images of complex environments such as high stress in the surrounding rock of the roadway and mining stress. The expansion mode and scale of the cracks determine the deformation and failure characterist...
