Abstract
The invention relates to the technical field of roadway surrounding rock monitoring, in particular to a method for monitoring roadway surrounding rock deformation based on three-dimensional laser scanning. The method comprises the following steps of: sequentially establishing a plurality of observation base points at a roadway bottom plate in an extension direction of a roadway; acquiring a firstroadway surrounding rock model at each observation base point through using a three-dimensional laser scanner; after preset time, further acquiring a second roadway surrounding rock model at each observation base point through using the three-dimensional laser scanner; and comparing the second roadway surrounding rock model with the first roadway surrounding rock model to obtain roadway surrounding rock deformation evolution characteristics. According to the method, non-contact high-speed laser scanning is carried out on the current state of the roadway by using the three-dimensional laser scanner at each observation base point; real-scene copying of the whole coal mine roadway can be achieved, comprehensive, dynamic and continuous observation of roadway deformation is guaranteed, the current state of roadway surrounding rock can be reconstructed in real time, roadway surrounding rock surface information at all observation base point positions of the roadway is compared and analyzed, and roadway surrounding rock deformation evolution characteristics are obtained.
Description
technical field [0001] The invention relates to the technical field of roadway surrounding rock monitoring, in particular to a method for monitoring deformation of roadway surrounding rock based on three-dimensional laser scanning. Background technique [0002] In recent years, due to excessive coal mining, my country's coal mines are generally in a state of large buried depth and high-intensity mining. The roadway is affected by mining, and the deformation of the surrounding rock is seriously convergent. The change period of the roadway surrounding rock is short and the deformation lasts for a long time, which seriously affects the coal mine Safe Production. Traditional roadway deformation monitoring devices such as laser rangefinders and multi-point displacement meters are single-point monitoring, which cannot form a comprehensive and effective monitoring of roadway surrounding rock deformation, which is not conducive to the research of roadway surrounding rock control tech...
