Split set rock bolt can be load tested by fitting a special ring to the bolt prior to its installation. Pull tests can then be conducted with a hollow ram hydraulic jack. 2.The installation is the simple. 3.No anchoring agent is required. 4.The friction strength between the bolt and the rock is large. 5.It has high shear and tensile strength.

Drill each hole at least 2 inches (5 cm) longer than the bolt Number each hole and record the bit size. In soft ground, a bit may drill a hole larger than its diameter. In hard abrasive ground, the hole may be the same diameter as the bit. Drive into each hole an SS-39 Split Set stabilizer fitted with a pull collar as shown.
