To solve the problems of long support time and low excavation efficiency in the current Wangping Coal Industry roadway excavation working face,firstly,based on traditional roadway support,theoretical research was conducted on the deformation characteristics of the surrounding rock and the spatiotemporal effects of the excavation face of the surrounding rock.Multiple support technologies were proposed,and studied from the perspectives of theoretical research and process analysis.Finally,through experimental comparison,the multiple support schemes increased the monthly excavation volume by 26.3％compared to the original scheme while ensuring the safety and stability of the roadway,achieving the goal of rapid excavation.
