Fully threaded FRP bolts for mining are produced according to the "MT / T 1061-2008 resin bolts, glass fiber reinforced plastic rod body and accessories" standard, mainly used for coal mine roadway support, with obvious advantages:
High strength and large anchoring force;
Lightweight and easy to transport;
Excellent cutability, no need to dismantle, ensuring the roadway mining efficiency;
Flame retardant
Anti-static, no spark cutting, to ensure the safety of coal production.
