1207材料巷锚网索支护参数设计与应用

Design and Application of Anchor Mesh and Cable Support Parameters of 1207 Material Roadway

采用理论计算方法确定了南关煤业1207材料巷支护锚杆长度、直径、间排距以及锚索长度、直径、间排距,设计了锚网索支护技术方案,于南关煤业1207材料巷现场试验。巷道移近量监测结果显示,采用设计的支护技术方案,实现了南关煤业1207材料巷围岩的稳定控制,表明了设计的合理性和可靠性。

By theoretical calculation method,the author first determines the length,diameter and interval of bolt and anchor cable,then designs the supporting technology scheme of anchor net and cable,which is tested in 1207 material roadway of Nanguan Coal Industry.The monitoring results of roadway convergence show that the stability control of surrounding rock of 1207 material roadway in Nanguan Coal Industry has been realized by using the designed support technology scheme,which indicates the rationality and reliability of the design.
