Description

technical field [0001] The invention belongs to the technical field of a deformation monitoring system for an underground coal mine roadway, and in particular relates to a deformation monitoring system and a monitoring method for an underground coal mine roadway. Background technique [0002] At present, the underground deformation monitoring method of coal mines adopts the method of roof abscission instrument and ruler measurement. A section is taken every 50m in the roadway, and four points are set on the section to measure the distance between the two gang points and the roof and floor points. The data is compared to obtain its deformation. When a large amount of deformation is found in a certain area, it is then encrypted, and the curve of the convergence amount of the two sides and the roof, that is, the convergence rate over time, is drawn through the measurement data, and the law of roadway deformation is obtained through analysis. This method cannot realize continuo...

AI Technical Summary

Problems solved by technology

This method cannot realize continuous monitoring of the deformation of the entire roadway, and there are problems such as unreal-time data transmission, incomplete data collection, unintuitive data form, and poor accuracy. and comparison function

[0003] The existing mine production management is based on two-dimensional data based on AutoCAD, which can no longer meet the requirements of transparent and refined management for production, and the existing three-dimensional modeling technology such as BIM is difficult to achieve fast and efficient modeling
