Rock Bolts and Self Drilling Anchor
Rock Bolts and Self Drilling Anchor
It is a long anchor bolt, and this technique is used to stabilize rock excavations, which can be used in tunnels or rock cuttings where it transfers loads from the outer, not strong rocky layer to the inner (strongest) layer of the rock mass. The rock nails technology was first used in the field of mining in the nineties 19th century Rock studs are almost always installed in a specific pattern, the design of which depends on the designation of the quality of the rock and the type of drill. Rock studs act as "weaving" blocks of rock together enough to prevent and tighten them from moving and budge enough to lighten their weight and mass through collapse (piece by piece)
