摘　　要：对某矿8106工作面5100回采巷道进行支护设计,通过理论计算综合确定锚杆支护方案。在5100回采巷道中设置测点,对巷道表面位移和顶板离层进行监测。监测结果发现:顶底板最大移近量为300 mm,两帮最大位移量为220 mm,巷道变形量相对较小;离层仪显示离层值绝大部分为0,有很少一部分的离层仪显示离层值为1~5 mm。因此,确定此次锚杆支护参数设计效果显著。The support design of 5100 mining roadway in No. 8106 face of a certain mine is carried out, and the bolting support scheme is determined synthetically by theoretical calculation. The monitoring results show that the maximum displacement of roof and floor is 300 mm, the maximum displacement of two sides is 220 mm, and the deformation of roadway is relatively small. Most of the dissociation values were 0, and only a few of them showed that the separation values were 1 ~ 5 mm. Therefore, the determination of the bolt support parameters design effect is remarkable.
