split set bolt installation

Oct 08,  · Installation can be done in a few easy step: 1.Drill the hole. 2.Replace the drill steel with a driver tool. 3.Slide the plate on the tube. 4.Drive the tube in with the drill / drifter Rock Bolt Pull Tests Prove Sustained Grip Pull tests help verify the effectiveness of the stabilizers upon installation and over periods of time.

Drill a hole slightly smaller in diameter than the Split Set stabiliser. · Ensure that the hole is drilled slightly deeper than the complete length of the bolt.

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

FB-42 SPLIT SET BOLT As an alternative friction bolt stabilizer of FB-47 Split Set Bolt used in applications, Dia.42mm has the same C shape of bolt body which can also offer a perfect and safety way for ground support as the FB-47 bolt does, also widely and popular used in rock and ground support

Split-SetK Bolt and Elliptical Bolt Sets *.****.*o* 94 Company of Butte, Montana, began making rock bolt installations in 1939. In.

The Split Set stabilizer installation is very easy and rapid as 1-2 ! 1- drill the hole. 2- drive the bolt until the plate is in contact with the rock. Split Set stabilizers, model SS39, can be

Easy Installation The Split Set is a popular choice due to its easy installation. Once the hole is drilled, the driver 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

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.

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

spot checks, to assure that proper installation techniques are still being used. 33 mm (15/ 16 in.) 32 mm (nom. 11/ 4 in.) 31 mm 30 mm (13/ 16 in.) Anchorage, tons 8 7 6 5 4 3 2 1 0 bolts. For this reason, the Split Set Group offers a free application engineering service to assist you in the selection of the proper Split Set configuration

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.

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 

Fast, easy installation takes usually less than a minute - just drill and drive. Split Set® stabilizers come in 3 models. They are available in lengths and sizes to meet your needs and are

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

Many underground mining operations use Split Set friction stabilizer bolts for rock support. Currently, however, little has been done to quantify the 

Split Sets are rock bolts with only 2 parts, a tube and matching domed bearing plate. The high strength steel tube is slotted along its length.
