摘要
针对开切眼跨度大造成工作面受到地质灾害的问题,以8702工作面为例,在研究其地质、顶底板情况的基础上,提出开切眼支护的原则,并结合现场情况完成锚杆+锚索+金属网的联合支护参数的设计,最后设计监测方案,对开切眼支护方案的有效性进行验证。实践表明,所采用的的支护方式应用效果良好。
In view of the geological disaster caused by the long span of open cut hole, taking 8702 working face as an example, on the basis of studying its geology and roof and floor condition, the principle of open-off cut hole support is put forward, and the joint support parameters of anchor cable metal mesh are completed according to the field situation. Finally, the effectiveness of open-off cut hole support scheme is verified by the design and monitoring scheme. The practice shows that the application effect of the supporting method is good.
