Support technology and device development of yield cables for the high stress and large deformation roadway
摘要
Abstract
Due to high stress and large deformation of deep roadway surrounding rock,the support system must have high-strength yielding characteristics. Deformation strength of yield device is equal to the limit of cable yield strength. So when the bearing capacity of cable goes up to or approaches the limit of yield strength, the yield device will respond firstly with yield strength reduction and displace-ment, and will release some energy, which makes it possible to avoid premature failure of over-load and keep surrounding rock of roadway long-term steady and to maintain its integrity. Simultaneously,the experiments to test mechanical property parameters of various yield devices have been done by using Rock Mechanics Test System MTS815. 3 types of yield devices for cables respectively match with cable support system in certain diameter (Φ15.24 mm,Φ17.8 mm,Φ18.9 mm) and strength. Engineering practice has shown that this support technology and success of new product development can protect the integrity of bolting mesh system effectively, and improve the quality and level of support for surround-ing rock of deep roadway.关键词
