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 

Load cells were placed on the head end of the bolts to determine head loads. Head loads up to 14.7 kN (3,300 Ib) were generated during bolt installation. In 

Split Set stabilizers are commonly installed with jacklegs, stopers, jumbos and automatic bolting machines. Almost any hydraulic drill, or any percussive air 

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

Dec 31,  · Installation Quality Guidelines of Split Set Stabilizer Friction Bolts. -12-31. The following are items to be aware of when using/installing friction stabilizers: Type of Ground - The nature of the ground must be evaluated. Soft strata requires a longer anchorage length to be effective. Soft ground results in larger hole sizes for a given

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.

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
