Mine cable bolt is composed of steel strand, anchoring agent, tray, anchorage and other anchoring accessories, which can exert active pressure on surrounding rock by mechanical tension.

Application range

Mine cable bolt is used in coal mine or other mines, roadway and surrounding rock circle. The bolt support form and parameters designed conventionally in mine roadway often fail to support effectively, which leads to the overall collapse of bolt support and brings serious consequences.

performance parameter

A static load anchorage performance of anchorage ?a?0.95 ?apu?2.0%

B fatigue load performance: meet 2 million cyclic loads;

C cyclic load performance: meet 50 cyclic loads.

D pull-out force of cable bolt: Tw > 1.05nt = 157.5kn

Transportation and storage

Mine cable bolts should be lightly unloaded during transportation, loading and unloading, and should not be thrown at will, so as to ensure that cable bolt products are not damaged or contaminated with oil. The cable bolt should be used as soon as possible after being manufactured, and should not be stored for a long time. If it needs to be stored, it should be placed in a dry and clean place to avoid corrosion and oil pollution caused by rain and water immersion.
