摘要
随着矿井开采深度不断增加,围岩稳定性变差,巷道支护难度增大,通过对深部巷道变形特性及破坏原因分析,按照"高强度、高刚度、高可靠性与低支护密度"设计原则,对巷道支护参数进行设计优化,有效地控制了巷道的变形破坏,达到了巷道支护效果。
With the mining depth increasing, the surrounding rock stability becomes worse, roadway supportdifficulty increases, this paper analyzed the deformation characteristics and failure reasons of deep roadway, inaccordance with the "high strength, high stiffness, high reliability and low density of support" the principle ofdesign, the roadway support parameters are optimized, effectively controlled the deformation and failure ofroadway, and achieved the roadway support effect.
