Research on Countermeasures for Supporting Deep Soft Rock Roadway
The problem of controlling the stability of deep soft rock surrounding rock is becoming more and more prominent.Taking Dongzhouyao coal mine as the study area,the deformation and damage characteristics of the roadway were obtained through field survey.The relationship between roadway deformation,surrounding rock inclination and the location of the weak layer was analyzed through numerical simulation,and the factors influencing the deformation and damage characteristics of the soft rock roadway were derived.Based on the numerical simulation results,a new design scheme of deep soft rock roadway support is proposed.The results show that the new support scheme has good control effect and is of guiding significance for similar projects.
