摘要
针对同忻矿5104巷道超前支护段压力显现强烈的情况,分析了煤层赋存、煤层顶底板、上覆采空区、工作面布置方式等各因素,采取了具有针对性的"支卸结合"控制措施,使5104巷道压力得到了有效的控制,经济效益和社会效益明显,可为开采相同条件的煤层借鉴。
By analysis of seam occurrence, seam floor and roof, overlying gob and layout of working face, the author proposes the corresponding control measures of retaining-and-relief combination in the advanced-supported section with strong strata behavior at 5140 roadway of Tongxin Colliery,which have effectively controlled the roadway strata with remarkable economic and social benefits.
