摘要
西部某矿井大型设备换装硐室施工断面大,掘进过程中支护效果成为保证硐室使用效果的关键,提出了换装硐室掘进支护设计方案。工程实践表明,硐室采用锚杆(索)全断面加强支护,锚杆能够保证硐室浅部范围内围岩的完整性,与锚索共同作用能够保证硐室围岩的稳定性。
The construction of underground chamber for large-scale equipment in a mine in west of China has a large section,the support effect in the excavation process is the key for normal use.A design scheme for the excavation and support is proposed.The engineering practice shows that the adoption of the full-section reinforcement of the anchor(cable)ensure the integrity of the surrounding rock within the shallow part of the chamber,and the stability of the surrounding rock of the chamber can be guaranteed.
