Rock bolt, in tunneling  ₩‍¥;and underground mi∞→φning, steel rod inser★→ ted in a hole drilled into the roof or£$ walls of a rock formation to↕₽∑ provide support to the roof or∏​ sides of the cavity. Ro↑←δ↔ck bolt reinforcement cΩ≥an be used in any excavation geometr☆<δy, is simple and qui↓<♥ck to apply, and is relatively inexpδΩ↑ ensive. The installation can be fully εσmechanized. The length of the bol↑®ts and their spacing can b ≠↕ e varied, depending on the r>≠≥Ωeinforcement requirements.

There are three major ways₹♣♠  of anchoring the rock bolts: me₽©λchanical, grouted, and friction. Tδ&±he most common groutαπσ↕-anchored rock bolt is the fully groute™♣ε∞d rebar, a threaded bar made of stee​$ε↑l. Cement or resin is used as th₹Ωe grouting agent. A cable bolt is a>↔♠↕ reinforcing element made of§≠₽ steel wires in the form of a s↑φtrand or rope; it is ↑♣∞φinstalled in the borehole with cement g"→↔rout.

Super high duty, ultra high s☆¶trength heat treatment rock bolt/ a•©nchor bolt/ roof support system is ¶γ‍₽an advanced steel products with ‍™​γprime quality and high performanα✘♥ce, which can ensure the <λ≈♦anchoring effect for✔♣ complex ground conditions€↔, such as sand and gravel to i≥"‌←nconsistent fill, boulders, rubble an§ §™d weathered rock. Raw materials are ho☆ ♦t rolled steel rebars or defo•÷rmed bars, using inducti$​ve heat treating technology （our pa÷₽tent）. This product is widely←♣ used in tunneling, mining, s✘©₽₽lope stabilization and fo→↕undation support.

Our high duty high strength rock"↕¥ anchor bolt product have higher 𕧠strength grade than norma λ≤≠l hot-rolled rebars( for exaα★mple, grade MG500,600,700,785,÷∏830 Mpa). This advan∑©tage of our product can decrease dφ≥eformation of rocks, contr★β₽®ol or limit the breakage area in s≈±πurrounding rock. It's goo ✔↑d anti-impact property can resist sud↓£♦✘den impact pressure, w←©hich can ensure the securi₩β±ty of mining operatiδ¥≥on.
