An innovative design of a twisted yieldable rock bolt has been developed using the system analysis of conventional rock bolt technology, a thermodynamic approach, and a theory of technical creativity. This bolt consists of one single piece of a metal cylindrical rod having longitudinal feathers that provided its maximal reliability and minimized the cost. The bolt can be driven into a hole with a pneumatic hammer and creates a set of dissipative structures during rock mass deformation that facilitates and intensifies the dissipation of ground pressure energy causing stress relief around an underground opening. A 30 cm section of the bolt was successfully tested in special laboratory equipment, one 1.8 m bolt in a mechanic workshop, and fifty-five 1.8 m bolts in an underground entry of a coal mine. The behavior of this bolt was simulated on the FLA3D model to verify its basic parameters and to understand deeper abilities to yield and resist rock mass deformation. This bolt is fastened to the hole's wall for its entire length, thus the resistance and the energy dissipation indicators of this bolt are extensive parameters, hence the 2-m-length bolt can exceed the performance of the best modern prototypes. This bolt is relevant to provide stability to underground openings in hard squeezing conditions.

利用传统锚杆技术的系统分析、热力学方法和技术创新理论，开发了一种扭曲可屈服锚杆的创新设计。该螺栓由一根具有纵向羽毛的金属圆柱杆组成，可提供最大的可靠性并最大限度地降低成本。螺栓可以用气动锤打入孔中，并在岩体变形过程中产生一组耗散结构，促进和加强地面压力能量的耗散，从而导致地下开口周围的应力释放。一段 30 cm 的螺栓在特殊的实验室设备中成功测试，一个 1.8 m 的螺栓在机械车间成功测试，55 个 1.8 m 的螺栓在煤矿的地下入口中测试。该螺栓的行为在 FLA3D 模型上进行了模拟，以验证其基本参数并了解更深层次的屈服和抵抗岩体变形的能力。该螺栓的整个长度都固定在孔壁上，因此该螺栓的阻力和能量耗散指标是广泛的参数，因此 2 米长的螺栓可以超过最好的现代原型的性能。该螺栓与在硬挤压条件下为地下开口提供稳定性有关。因此，2 米长的螺栓可以超过最好的现代原型的性能。该螺栓与在硬挤压条件下为地下开口提供稳定性有关。因此，2 米长的螺栓可以超过最好的现代原型的性能。该螺栓与在硬挤压条件下为地下开口提供稳定性有关。
