Cable bolt The length of cable bolt varied between 3 to 15 meters and is manufactured with wires of high carbon toronado (EHT) and heat mechanically treated with a low relaxation process Cable bolt configuration most used by mining is made up of 6 wire wound around a seventh called "soul" or strandBy combining the support capabilities of a standard 7-strand cable bolt with a miniature 6-wire extensometer, the SMART (Stretch Measurement to Assess Reinforcement Tension) Cable was born The stretch in the cable is determined via the integrated six-point extensometer, allowing the strain between the anchor points to be calculated.
