Mining Underground Split Sets
- -The raw material is made of high-strength alloy steel strip.
- -The installation is the simple.
- -No anchoring agent is required.
- -The friction strength between the bolt and the rock is large.
- -It has high shear and tensile strength.
Mining Underground Split Sets
Mining Underground Split Sets has many advantages such as consolidate a surrounding rock on self's own initiative,active reinforcement anchorage and immediately bearing etc. Mining Underground Split Sets is installed in a hole which has smaller diameter than it.It can immediately impose full range radial pressure on the wall of the hole to prevent rock fall.In case of blasting vibration displacement of surround rock,anchoring increases significantly,and supporting effect is ideal.
Mining Underground Split SetsTechnical advantage
High-strength tray beraing capacity,the rod body than retaining ring pull off the bearing force than pole.
