摘 要:锚杆支护设计对于控制巷道围岩变形和破坏,维持巷道围岩稳定起着决定性的作用。根据工作面实际地质条件和开采条件,采用理论计算和数值模拟相结合的方法对巷道进行初步锚杆支护设计,然后进行现场工程实践和矿压观测。通过对矿压观测数据进行分析,优化了初步锚杆支护设计方案,从而得出合理的锚杆支护设计方案,使巷道围岩变形得到有效控制,满足了矿井实际生产需要。The design of bolt supporting plays a very important role on controlling deformation and destroy of surrounding rock in roadway.Based on geological conditions and mining conditions of working face,the preliminary bolt supporting design was established by adopting the method of theoretical calculation and numerical simulation,then the industrial practice and the mineral pressure observation were implemented.By analyzing the data of mineral pressure observation,the preliminary bolt supporting design was optimized,so the reasonable bolt supporting design was found and the deformation of the surrounding rock was controlled effectively,which met the demands of practical production of mine shaft.
