摘　　要：针对铁峰煤业增子坊煤矿5305工作面接近断层时遇到的支护失效、巷道变形等问题,为确保施工安全,对工作面制定了锚固剂+锚杆+钢带+钢棚+锚索联合支护等针对性的补强支护方案,有效地增加工作面围岩的稳定性。后期生产中顶板变形、下沉以及与底板的相对移近量减少,锚索和锚杆支护作用增强,顶板事故明显减少,保证矿井安全生产。In response to the problems of support failure and roadway deformation encountered when the 5305 working face of Tiefeng Coal Industry Zengzifang Coal Mine approached the fault,in order to ensure construction safety,targeted reinforcement and support plans such as anchor agent+anchor rod+steel belt+steel shed+anchor cable combined support were developed for the working face,effectively increasing the stability of the surrounding rock of the working face.In the later production,the deformation,sinking of the roof and the relative displacement with the bottom plate decreased,and the support effect of anchor cables and anchor rods was enhanced.The number of roof accidents has significantly decreased,ensuring the safety of mine production.
