摘要
利用理论计算的方法对3603工作面超前支承压力分布进行了计算,对运输顺槽超前支承压力影响范围进行了分区,确定了“顺槽围岩超前段分区强化支护原则”,设计了支护强化技术参数,现场实测表明,巷道表面位移均处于安全范围之内。
By using the method of theoretical calculation of 3603 working face advance abutment pressure distribution was calculated, and the transport gateway has carried on the partition scope of abutment pressure, determine the "gateway surrounding rock ahead of the partition to strengthen supporting principle", design parameters, the supporting technology field measurement show that the surface displacement of roadway in safe range.
