39mm Mining Rock Split Set Bolt FRICTION ROCK ANCHOR BOLTS Roof
Support for Mine Seam Pipe
Product Description
Split set is also know as friction bolt.
It is a rock support method used in underground mining and tunnel
construction.The bolt consists of a high strength steel bolt with a
''U'' shape cross section and a longitudinal groove.
To install a Split Set bolt, a hole is made in the rock with a
diameter slightly smaller than the bolt’s diameter, and the Split
Set is inserted into it. As the bolt is pushed into the rock, the
“U” shaped cross-section reduces and adjusts to the shape of the
borehole. This expansion creates friction between the Split Set and
the surrounding rock along its entire length, providing strong
resistance to displacement
