Coal mine slotted anchor

Pipe seam anchors Seam pipe anchors Slotted anchor rock friction stabilizer main specifications
Length
Pipe seam anchors are mainly used for relatively complete rock mass roofs, with diameters of,,,,,, Six series.
Technical features
The raw material is made of high-strength alloy strip steel
The installation is simplest
No anchoring agent is needed
The friction between the anchor rod and the rock mass is large
>. It has high shear resistance and tensile strength
. It is equipped with a high-strength pallet. The pallet is evenly stressed
and the height of the tunnel is greater than the length of the anchor rod.
