新元矿软岩硐室通道支护方案设计

Design of Support Scheme for Soft Rock Chamber Channel in Xinyuan Mine

针对阳煤新元副井南翼中央轨道大巷硐室通道掘进施工段围岩强度低和承载能力较差的问题,对锚杆、锚索支护参数进行设计,并进行了喷浆加固。现场监测结果表明:在进行支护后两帮围岩移近量稳定在208mm左右,顶底板围岩移近量稳定在189mm左右,成功实现对围岩变形的有效控制。

Aiming at the problems of low strength and poor bearing capacity of surrounding rock in the heading section of South Wing central track roadway of Xinyuan auxiliary shaft in Yangquan Coal Group, the supporting parameters of bolt and anchor cable were designed and shotcrete reinforcement was carried out. The feld monitoring results show that the approaching displacement of the surrounding rock of the two sides is about 208 mm and the approaching displacement of the surrounding rock of the roof and foor is about 189 mm after the support is carried out.The effective control of the deformation of the surrounding rock is successfully realized.
