摘要
锚杆加固是煤矿中一种主动支护的形式,代表了巷道支护的发展方向。在煤矿基础设计中,锚杆加固理论是设计的基础,是支护设计的关键部分。本文以碱沟煤矿为研究对象,在深入了解锚杆加固机理的基础上,分析了矿井中煤柱力学状态,并结合实际工程实例进行计算,得出岩体在加固前后的强度值,为煤柱锚杆加固的研究提供一定的参考。
Anchor reinforcement of roadway support. In the foundation is an active support in the design of coal mine, bolt lorm oI a coal mine, represents the development direction reinforcement theory is the basis of design, is a key part of the supporting design. Alkali ditch coal mine as the research object in this paper, on the basis of insight into the bolt rein forcement mechanism, the mechanical state of the coal pillar in coal mine are analyzed, neering example is calculated and concluded that the strength provides certain reference to the research of coal pillar anchor of the rock mass before reinforcement. and combined with practical engi- and after the reinforcement value,
