煤矿巷道锚杆支护参数设计研究

Design of Anchor Support Parameters for Coal Mine Roadway

煤矿巷道的锚固支护直接决定着井下作业人员的生命安全,关系着生产效率。锚杆支护理论和技术在实际中不断地应用和创新。以矩形截面巷道不稳定巷道为研究对象,利用锚杆支护原理和工程类比经验,进行了锚杆支护方案设计和锚杆参数设计。实践表明,新设计的方案能够满足实际需求,保障巷道作业安全。

The anchor support of coal mine roadway directly determines the life safety of underground operators and is related to the production efficiency.Anchor support theory and technology are constantly applied and innovated in practice.Taking the unstable roadway with rectangular cross-section as the research object,the anchor rod support scheme design and anchor rod parameter design were carried out by using the anchor rod support principle and engineering analogy experience.The practice shows that the newly designed scheme can meet the actual demand and guarantee the safety of roadway operation.
