摘要
为了有效控制深部高应力巷道与软岩大变形巷道,防止冲击地压等矿井灾害的发生,设计一种吸能防冲锚杆支护构件。主要利用了金属圆管轴向撕裂卷曲变形的吸能特性,介绍了吸能防冲锚杆支护体的结构组成与工作原理,建立了吸能支护构件的力学结构理论模型,研究了其吸能特性及效果。
In order to effectively control the deep high stress roadway and soft rock large deformation roadway, and to prevent the occurrence of mine disasters such as rock burst, a kind of energy absorbing rock burst prevention bolt support component was designed. Mainly used the energy absorption characteristics of the axial tearing and curling deformation of the metal pipe, introduced the structure composition and working principle of the energy absorption and rock burst prevention bolt support body, established the mechanical structure theoretical model of the energy absorption support component, and explored its energy absorption characteristics and effect.
