Abstract
Aiming at the existing force monitoring problem of roadway anchor rods in Gaozhuang Coal Industry,an intelligent perception system based on fiber raster technology is proposed.This system designs a new type of desensitization fiber raster force measuring anchor rod and fiber raster anchor rod(cable)dynamometer,which solves the problem of traditional rasters being easily damaged.The on-site application of the 113upper05 working face in Gaozhuang Coal Industry Company shows that the system can monitor the load changes in anchor rod in real time and provide accurate deformation data of roadway surrounding rock;when the anchor rod is pushed to a distance of 90-180 m from the working face,the anchor rod load remains basically stable.However,when the anchor rod is pushed to a distance of 12-40 m from the working face,the anchor rod load occurs a significant rising,reflecting the significant impact of mining.This proves the feasibility and effectiveness of fiber raster technology in coal mine safety monitoring,providing reliable data support for roadway support optimization.The initial anchoring force and anchorage force of the anchor rod are significantly rised,respectively,improving the safety production level of the mine.关键词
