4, minor space requirement for the accomplishment of anchoring
5, optimized machinery and manpower requirements
6, basic dimensioning of the required anchoring forces by choosing
the appropriate anchor type
7, optimum bonding of the profiled anchor rod and the grout
8, adjustment of the drill bit design and diameter to different
rock mass and ground conditions
9, simple anti-corrosion method available
