摘　　要：针对3209综采工作面沿空送巷采动影响范围大、围岩裂隙较发育和煤柱稳定性较差等实际特点,提出了掘进巷道采用锚网索带联合支护方式,沿空侧帮部采取加长锚杆配合钢带、钢筋网支护,有效控制了围岩变形。回采时,该巷道采用单体棚、履带式液压支架和墩柱式液压支架联合超前支护,取得较好效果。Aiming at the actual characteristics of the 3209 fully mechanized mining face, such as large range of mining influence, relatively developed cracks in surrounding rock and poor stability of coal pillar, the combined support mode of anchor, wire mesh and cable belt is put forward in the driving roadway. Along the goaf side, lengthened anchor rods combined with steel belt and steel mesh support are adopted to effectively control the deformation of surrounding rock.During mining, the roadway adopts the combined advance support of single shed, crawler hydraulic support and pier hydraulic support, and good results are obtained.
