ABSTRACT

This article discusses the design principle, scheme implementation and stability evaluation of coal mine roadway supporting structure. Firstly, according to the geological conditions, cross-section shape and service life of the roadway, the composite supporting structure combined with anchor net cable and scaffolding is designed comprehensively, and the specifications, layout and construction technology of supporting materials are expounded. Subsequently, the stability of the supporting structure is analyzed by combining numerical simulation with field monitoring. The numerical simulation results demonstrate that the composite support form significantly controls surrounding rock deformation, with field monitoring data validating the support design's rationality. Additionally, the paper analyzes factors influencing the stability of the supporting structure and offers optimization suggestions, providing a scientific foundation for the long-term safe use of coal mine roadway.
