Mining rock bolts are a crucial member of the anchoring family, primarily made from high-strength, low-relaxation steel strands. Because they can provide strong pre-stress, they effectively balance the sliding force of slopes, ensuring slope stability meets the safety requirements of engineering construction. Mining rock bolts are a prestressed device composed of steel strands, plates, anchoring devices, and other accessories, applying active pressure to the surrounding rock through mechanical tensioning.

I. Product Applications

Used with resin glue, they are mainly used for reinforcement of coal mine roadway surrounding rock and broken coal seams in the roof. The broken surrounding rock and coal seams can be anchored as a whole; the post-tensioned structure of the pre-stressed steel bar anchoring can meet the pre-tensioning force required for support, thus achieving the purpose of overall support.

II. Product Features

Features high strength, fast support, and ease of use. Particularly suitable for coal mine roadway support projects.

III. Transportation and Storage

(1) Mining rock bolts should be carefully handled during transportation and loading and unloading; they must not be thrown around.

(2) Rock bolt products should be free of damage and oil stains.

(3) Rock bolts should be used as soon as possible after manufacturing and not stored for extended periods. If storage is necessary, they should be placed in a dry, clean place to avoid corrosion and oil stains caused by rain and water immersion.

IV. Mining Cables

Using rock bolts in support operations allows anchoring into deep, stable rock layers and applying pre-load. It's a reliable, proactive support favored by many in the mining industry. I hope you too can use reliable and affordable mining rock bolts.

Mining rock bolts are equipment used to reinforce the surrounding rock of coal mine roadways, consisting of steel strands, anchoring devices, and other accessories. In recent years, mining rock bolts have been widely used in roadway support, embankment reinforcement, slope treatment, deep foundation pit support, and tunnel reinforcement. Particularly in coal industry roadway construction, rock bolt support has rapidly developed due to its unparalleled technical advantages, support strength, and reliability. The introduction and application of this technology allows us to find useful support methods for special projects such as soft rock roadways, roadways in goaf areas, deep roadways, large cross-section chambers, working face openings, and roadway intersections.

Mining rock bolts also significantly improve and expand the stress conditions and application scale of new anchor net support technology and greatly reduce the workload of roadway protection and repair. Mining rock bolts (prestressed anchoring devices) are mainly used in the excavation process of mine roadways. The unstable rock layers below are suspended in the stable rock layers above via rock bolts, improving the surrounding rock strength and preventing wall spalling and roof collapse, ensuring safe production. In addition, other series of single-hole or multi-hole prestressed anchoring devices produced are also widely used in the construction of high-rise buildings, large-span factories, and bridges. Our company's anchor production line is equipped with advanced CNC machine tools and other advanced precision processing equipment, with strong product processing capabilities, high precision, and excellent quality.
