摘　　要：针对口孜东矿煤层埋藏深、地压大、煤仓所受冲击力大、损坏维修对生产影响大等问题,采用“锚网索喷+36U型井圈+铁钢砂钢筋砼+壁后注浆”的超强复合支护技术,保证了仓体的支护强度,提高了煤仓抵抗煤矸冲击的能力,对类似条件下施工具有一定的参考价值。In view of the problems such as deep burial of coal seam,high ground pressure,great impact on coal bunker and great influence of damage and maintenance on production in Kouzidong Coal Mine,the super composite support technology of"anchor mesh cable shotcreting+36U type well ring+iron steel sand reinforced concrete+back wall grouting"is adopted.It ensures the support strength of the bunker,improves the ability of the bunker to resist the impact of coal and gangue,and has a certain reference value for construction under similar conditions.
