摘　　要：以增子坊矿5#层303皮带巷过F_(1)、F_(2)等断层为工程实例,为确保巷道过断层期间围岩稳定,采用主动支护、被动支护等联合支护方式。拟定围岩支护参数,采用以锚+网+索+带+喷为主的主动支护,可提升围岩稳定性,降低断层涌水给巷道围岩控制带来的影响;采用以钢架梁为主的被动支护,可在一定程度上提升主动支护稳定性。现场应用表明,巷道过断层期间围岩稳定,顶底板、巷帮变形量均在允许范围内,围岩控制效果良好,可为其他矿井回采巷道掘进过断层提供经验借鉴。To ensure the surrounding rock stability in crossing F_(1) and F_(2) at 303 belt lane in No.5 coal seam of Zengzifang Colliery,the author proposes the active support of bolting and shot-creting with wire mesh to improving the stability of surrounding rock and reducing the influence of fault water inrush on surrounding rock control and the passive support with steel-frame beam to increase the stability of active support to some extent,whose field application shows that the deformation of roof,floor and sides can be controlled within allowable range in crossing fault with good effect of surrounding rock control.
