剪胀锚固理论在上社煤矿回采巷道锚固设计中的应用

The Application of Dilatancy Anchor Theory on Anchor Design in Mining Roadway of Shangshe

剪胀锚固理论是太原理工大学矿业工程学院贾喜荣教授提出的一种新的锚固理论,应用该理论计算分析方法,对上社煤矿9号煤层和15号煤层的回采巷道进行了锚固计算分析和锚固设计。工程应用结果表明设计方案能够满足工程要求。以上社煤矿15号煤层回采工作面进风巷锚固设计为例,给出了顶板岩层锚固强度的设计计算方法。

Professor Jia Xirong of Taiyuan University of technology put forward the dilatancy anchor theory as a new anchor theory. Using this theoretical calculation and analysis method, we made calculation, analysis and design of the 9th and 15th coal bed in mining roadway. The results of engineering application indicated that the design program satisfied the demands of engineering. In this paper, we also took the anchor design of mining roadway in number 15 coal bed as an example to give the calculation method of designing on the strength of the roof strata anchor.
