PT Hagita is the Distributor of Stiff Split Set Bolt in Indonesia (Australian product)
The purpose is to develop a system to install pre grouted Friction Bolts using the existing equipment and methodology of regular Friction Bolts. Without compromising ease of installation, compatibility with mesh and shotcrete, overall productivity and increasing the level of safety provided. Split set mining system is a company headquartered in Australia and produces underground roof support equipment, especially rigid split set bolts.
STIFF SPLIT SET
Typical 46mm Split Set Stabiliser
• Failure strength of the steel +/-18t
• A pull out resistance of approx. 4t permetre of o embedment is normal
• The bond, and performance of the bolt, is dependent upon the friction created between the bolt and the rock.
• Easy installation and reduced installation costs
• A bolt with one metre of embedment can holding, at best a rock weighing 4t Bolts pull out of the hole well before they break
Grouted Split Set Stabiliser
• Performance can be greatly improved by grouting the inside of the bolt using a thick, strong grout.
• This occurs because Split Sets conform to the shape of the borehole in which they are installed and the grout, once set, locks the shape/dimensions of the Split Set in the hole
• A typical 45mm borehole varies +/- 1mm along its length
• In order to remove the grouted bolt from the hole either the grout, the steel, the rock or some combination of these three, needs to fail
COMBI PLATE
Combi Plate is a kind of combination plate for use with Split Set Bolt (Friction Bolt Stabilizer) used to support rocks and makes the split set system have better supporting performance, and can improve the mesh Plates are able to follow shape wall when installed with pressure 115-195 Mpa. Two types of Combi Plate GALVANIZED and BLACK
