为适应矿井软岩大变形、岩爆大变形、冲击大变形、突出大变形的巷道支护,在以何满潮教授为首的科研团队指导下,生产出恒阻大变形锚杆(索)。本文介绍了恒阻大变形锚杆(索)的结构、工作原理、特性及技术参数。现场试验表明,恒阻大变形锚杆(索)可应用于矿山开采、交通、水利等工程领域引发的塌方、岩爆、冲击等灾害防治,具有广阔的推广应用前景。
In order to adapt to large deformation of soft rock in mine, large deformation of rock burst, large deformation of impact and prominent large deformation of roadway support, under the guidance of a research team headed by Professor He Manchao, a constant deformation and large deformation anchor rod (cable) is produced. This paper introduces the structure, working principle, characteristics and technical parameters of large deformation and constant deformation anchor rod (cable). Field tests show that the large deformation and constant deformation anchor (cable) can be applied to the prevention and control of landslides, rockbursts and impacts caused by the mining, transportation, water conservancy and other engineering fields and has broad prospects for popularization and application.
