摘　　要：针对葫芦素矿井箕斗装载硐室的工程地质条件,采用数值模拟方法,对硐室动态施工、生产振动、围岩蠕变特性进行了深入的分析。提出了预注浆、锚网索喷与钢筋混凝土砌碹的联合支护技术,成功解决了软岩条件下特大型硐室结构设计与围岩稳定控制难题。该研究对类似条件下的大硐室设计具有重要的借鉴意义。Aiming at engineering geological conditions of skip loading chamber in Hulusu coal mine,a comprehensive and in- depth analysis is conducted for chamber dynamic construction, production vibration, creep characteristics of surrounding rock, using numerical simulation methods, a combined support scheme is proposed using pre- grouting,anchor net cable spray and reinforced concrete lining. The study solved difficulty of structural design and surrounding rock control of large skip loading chamber in soft rock.
