Abstract: According the characteristics of large buried depth,high stress and low strength of surrounding in deep soft rock roadway of Pingdingshan No.1 Mine,it is difficult to ensure the long-time stability of the roadway by traditional anchor cable support technology. Based on the high-strength anchor-injection support material and optimized grouting process parameters, a strong anchor-injection support technology was proposed, with a 25 mm diameter full-threaded high-strength hollow grouting anchor and a 29 mm diameter hollow rib hollow grouting anchor. As the core full-section anchor-integrated support scheme, high-strength support, high-ash-water ratio, high-pressure diffusion, and large-scale anchor-reinforcement support technology are adopted. Field engineering tests show that the strong anchor and bolt support realizes the full anchorage of the anchor/anchor, strengthens the mechanical connection with the surrounding rock, improves the integrity and bearing performance of the surrounding rock of the roadway, and reduces the deformation of the roof by more than 40%. The surrounding rock deformation of the roadway under complicated and difficult conditions is effectively controlled, and the construction process is simple and the cost is low.
