摘要
目前锚喷支护已经成为煤矿巷道支护设计首选的支护形式,但是对于软岩巷道应运用软岩支护理论,针对不同类型的软岩,采取不同的设计对策。本文借用大雁三矿在设计中采用先让后抗、柔让适度,适时支护的二次支护原则的实例,阐述膨胀性软岩巷道支护采用锚喷支护的设计方法,并在实践中取得成功。
The shotcrete-bolt support is a special kind of support used for design in mine roadway supporting. Based on the soft rocks supporting theory, the different kind of designing countermeasures is adopted in different kind of soft rocks. Take Dayan No.3 coal mine as example, the coal mine design is applied to adopt the principle of second supporting for keeping a certain distance first and then resist, suitably flexible and keeping, timely supporting. The shotcrete-bolt support designing method in swelling soft rocks mine roadway supporting is described, and successfully applied in practice.
