摘要
软岩巷道具有大地压、大变形、难支护的特征。通过软岩巷道变形破坏机理研究 ,提出化学锚注支护控制对策。并对化学锚注支护技术原理、设计方案、技术参数、工艺配方、注浆效果检测、安全性能等进行研究 ,实施后控制了围岩强烈变形 ,保证了巷道的稳定
Soft rock headings are characterized by high ground pressure, high deformation and difficulties in supporting. Countermeasures are presented for chemical bolting and grouting of soft rock headings on the basis of research into the mechanism of the deformation. Research is also made on the principle, designing, technical parameters, formulation and preparation, result testing and safety performance of chemical bolting and grouting. The application of this technology has placed the severe deformation of enclosing rock under control and ensured the stability of headings, resulting in remarkable economic benefits.
