摘要:
以魏家地煤矿二号石门西下水仓返修工程为依托,通过现场勘察、理论分析、数值模拟、现场试验与监测等手段研究了复杂条件下煤矿大巷返修支护技术,提出了用于复杂条件下煤矿大巷返修的留设柔垫层让压联合支护技术。现场试验与监测研究表明,锚注以及留设柔垫层让压联合支护可限制围岩的变形,提高围岩支护体的共同承载能力,巷道返修支护方案设计合理,效果良好。
Abstract:
Based on Weijiadi mine No.2 cruss-cut West water storage repairing engineering, through on-site investigation, theoretical analysis, FLAC numerical simulation, field tests and monitoring metheds to study the supporting technology for repairing the main roadway in mine under complicated conditions,and the leaving in flexible cushion for combined yield supporting technology for repairing the main roadway in mine under complicated conditions is proposed. Field test and monitoring showed that bolt-grouting and leaving in flexible cushion for combined yield supporting can restrict the surrounding rock deformation, and improve the surrounding rock carrying capacity of the joint body.Repairing roadway support method is reasonable with good effect.
