... (also called Superstrand cable), Plain SUMO, Indented SUMO, Spiral MW9 and Plain MW10 cable bolts. These cables were tested subjected to different pretension loads. Concrete blocks with Uniaxial Compressive Strength (UCS) of 40 MPa and Stratabinder grout were used for all the tests to maintain test...

... ABSTRACT: In underground coal mines, rockbolts and cable bolts are two dominant forms of support elements to prevent instability of the surrounding rock mass. Using these steel anchoring elements with high strength and toughness provides better rock reinforcement in high stress environment...

... Laboratory pull-out tests of cable bolts are conducted using specimens of two types of cables made of plain and bulbed strands installed in steel pipes filled with cement grout. In order to investigate the mechanical behaviors of cable bolts and the mechanism of grout bond failure, the pressure...

... stability predicted by empirical methods was carried out. The empirical models indicated that in massive pyrite, dip spans in excess of 27m would probably require pre-reinforcement with cable bolts. Those stopes with dip spans exceeding 70m could anticipate serious ground control problems, despite cable...
