摘要
为了保证15212工作面回撤通道围岩稳定性,防止受工作面采动影响回撤通道围岩出现破碎、变形现象,根据实际支护现状提出了"锚杆(索)+锚索吊棚+柔性纤维网+单体柱"联合支护技术.实际应用效果表明,采用联合支护技术后回撤通道受采动影响不明显,有效控制了回撤通道变形现象,取得了显著应用成效.
Abstract
In order to ensure the stability of the peripheral rock of the retreat channel of 15212 working face and prevent the peripheral rock of the retreat channel from crushing and deformation under the influence of the mining movement of the working face,the joint support technology of"anchor rods(ropes)+anchor rope trellis+flexible fibre mesh+monolithic columns"has been proposed in accordance with the current situation of the actual support,and the effect of the actual application shows that:after the adoption of the joint support technology,the retreat channel is not obviously affected by the mining movement,and the support technology can effectively control the retreat channel.The actual application effect shows that:after adopting the joint support technology,the retreat channel is not obviously affected by the mining movement,and the deformation phenomenon of the retreat channel is effectively controlled,which has achieved remarkable application results.
