Stability Control Technology for Surrounding Rock of Soft Rock Mining Access Based on Time Effect Characteristics
This study aims to address the stability control issues of soft rock tunnels,with an actual case as the main research subject.Firstly,the basic characteristics of soft rock tunnels and the results of physical composition testing of surrounding rocks were analyzed.Based on this,comprehensive research was conducted on the stability control technology of soft rock tunnel surrounding rocks,laying a foundation for ensuring safe mining production operations.The research shows that due to long-term mining pressure,soft rock tunnels will experience certain deformation,with serious sinking of the arch top position and bulging on both sides.Through comprehensive mechanical testing,it was found that the rock strength of the tunnel surrounding rocks is relatively low and requires the introduction of rigid-flexible coupling dynamic reinforcement technology to ensure its stability.The application of this technology can improve the mechanical properties of the surrounding rocks,ensure their integrity and stability,and effectively enhance their bearing capacity,thus comprehensively improving their stability.
