Anchor cable support is an active support technology that transfers the stress of the surrounding rock to the stable deep rock layer through the combination of prestressed steel strands and grouting materials. This technology is widely used in coal mine tunnels, mine workings, and foundation pit projects, and achieves stable control of the surrounding rock by applying the suspension theory and combined arch theory. Its core advantages lie in the ability to form a joint support system with anchor rods and metal nets, and enhance the integrity of fractured rock masses through the grouting process. In complex geological conditions, the application of high-pressure jet grouting hole formation and follow-up pipe drilling technology has solved traditional construction problems. In the design of support parameters, factors such as rock layer characteristics, anchor cable length and spacing need to be comprehensively considered to ensure the safety of the project.
