Designing a cable bolt support system in a highly fractured rock mass experiencing significant stress changes from mining requires careful consideration of several key engineering factors. Cable bolts are long, high-strength steel cables that are grouted into boreholes to reinforce the rock mass. They provide support over a larger area than traditional rock bolts, making them suitable for challenging ground conditions. One key consideration is cable bolt length and spacing. In a highly fractured rock mass, the cable bolts must be long enough to extend beyond the zone of fractured rock and anchor into more competent, stable ground. The spacing between cable bolts must be close enough to effectively reinforce the fractured rock and prevent it from unraveling. The specific length and spacing will depend on the fracture density, the size of the unstable rock blocks, and the expected ....
