摘要

Hagan (2003) stated that the relationship between the diameter of the support hole and the diameter of the rockbolt has a large effect on the efficiency of reinforcement. The difference between the radius of the support hole and the radius of the bolt is known as the annulus size. Since the design diameter of the rockbolt is 25 mm, the design annulus size is 3.5 mm. According to the mine support standard, the required annulus size should not be greater than 5 mm. The design annulus size of 3.5 mm is within the required range as stipulated in the mine's code of practice. The design annulus size is also within the manufacturer's recommended optimal design annulus size of between 3-4 mm. From this observation, the design is anticipated to be highly efficient.
