【摘要】：建立在锚网喷支护和钢管混凝土支架高强度支护基础上,提出巷道承压环强化支护模型及理论,阐述了承压环的概念,建立承压环的力学模型,并对承压环结构的承栽能力进行理论分析,最后对深井软岩巷道承压环进行分类并提出相应的支护设计方法,巷道承压环强化支护理论作为新的深井巷道支护概念,对于深井软岩巷道支护机理的分析和实际支护工作具有重要意义。
[Abstract]:On the basis of bolt-mesh shotcreting support and high strength support with concrete filled steel tube support, this paper puts forward the model and theory of strengthened support for roadway bearing ring, expounds the concept of pressure ring, and establishes the mechanical model of pressure ring. The bearing capacity of bearing ring structure is analyzed theoretically. Finally, the bearing ring of soft rock roadway in deep shaft is classified and the corresponding supporting design method is put forward. The theory of strengthened supporting ring in roadway is regarded as a new concept of roadway support in deep well. It is of great significance to analyze the supporting mechanism of soft rock roadway in deep well and to support it in practice.
