Every kind of underground mine uses Split Set® friction rock bolts for mining and ground support. Miners use them for mine roof bolting and mine roof support as well as to pin mesh, hang conveyors, hold pipes, and cables, secure rails in place, and for other needs. Ground Support for Tunnels and Other Excavations

This paper shows that Jumbo installation of expanding friction rockbolts is now possible with the same ease as traditional 'Split Set' style friction bolts.

FB-39 SPLIT SET BOLT As a main reliable ground support Split Set Bolt used in applications, Dia.47mm C pipe of bolt body is the most crediable and reasonable size which can offer a perfect and safety way for ground support, so it is widely used in

Min. Order: 100 Set/Sets; Product Description Split set bolt, also called split set stabilizer, is an indispensable advanced material for underground mining support. Split set bolt is a very specific support product, and it is an advanced material used for the support of the roof of the underground copper or gold mining and other projects.

The increased load transfer capacity of the grouted bolts provide an alternative for permanent excavation support using split sets stabilizers.

The installation of Split Set stabilizers is a fairly straight-forward procedure and can be performed easily by trained personnel. The diameter of the bit should be measured and the length of the hole should be at least two inches longer than the bolt.

The length chosen should be the same as with other types of rock bolts, and installed with the same spacing. The stabilizer is installed with the same drill 

Our MF47 Split Set Bolt was made by high strength steel strip which special refined with very low level of Si & P in chemical components, it will make the bolt in perfect performance of supporting rocks, and help to have a good quality in galvanizing. 2.The installation is the simple. 3.No anchoring agent is required. 4.The friction

47mm Split Set Bolt is a underground mining support product. It has simple installation process and convenient use. It has strong anchoring force and tensile strength in underground mining and shotcrete support. It has Large force, strong expansion force. 47mm Split set bolt has good supporting effect.

Both field and laboratory tests show that the load capacity of a Split set is approximately 50 kN/m (Cheng and Feng, 1983; Myrvang and Hanssen, 1983; Player et al., ). Therefore, it is said

Drill each hole at least 2 inches (5 cm) longer than the bolt Number each hole and record the bit size. In soft ground, a bit may drill a hole larger than its diameter. In hard abrasive ground, the hole may be the same diameter as the bit. Drive into each hole an SS-39 Split Set stabilizer fitted with a pull collar as shown.

Split Set / Friction Bolts are available in 33mm, 39mm, 41mm and 46mm diameters in a variety of lengths to suit the application of the mine. The domed bearing washer plates are available in 125 x 125 x 4mm and 150mm x 150mm x 4mm as well as the Combi Washer Plate 300mm x 270mm x 1.6mm.

A system of twelve equations have been developed for the elastic-plastic analysis of split-set roof bolts and these equations have been programmed for 

Cable bolts with one or several steel or geosynthetic fibres connected to the rock mass via cement or resin. 4 Popular bolt types. Split set anchor.

Miners need to optimize the bolt installation in keeping reliable rock support capacity. By using the METAL SERVICE Offset Driver with Jackdrill to install Split Set stabilizers (model SS39) , you can save 60 to 70 cm in low head room or narrow veins situations. The Offset Driver will help to keep the Split Set alignment. Split Set® utility hangers
