巷道破碎带锚索穿棚协同支护技术应用

Application of Anchor Cable through Shed Collaborative Support Technology for Roadway Fracture Zone

基于马兰矿北三下组煤采区右翼轨道巷在掘进过断层期间,出现围岩破碎现象,导致巷道成型效果差,单一锚杆(索)支护效果差、失效率高等技术难题,马兰矿通过技术研究,决定对巷道破碎区采取锚索穿棚协同支护技术。通过实际应用效果来看,采用协同支护技术后控制了围岩变形现象,取得了显著应用成效。

Based on the technical problems of poor channel formation,poor effect of single anchor rod(rope)support and high failure rate,the Malan Mine decided to adopt the anchor rope through shed cooperative support technology for the broken area of the channel through technical research.The practical application results show that the collaborative support technology has controlled the deformation of the surrounding rock and achieved significant application results.
