Due to roof bolts failures when supporting roofs during mining operations, there was need for quality assurance for the bolts to be investigated. The key bolt parameters were bolt length, diameter, rib angle, rib height, rib spacing and washer/plate thickness. Finite element analysis method was used to simulate, the failure was found to be due to high load. The new bolt design was generated and tested for the capacity of withstanding the load.
