The split set stabilizer is a type of rock bolt that is commonly used in underground mines to provide support to the surrounding rock mass. It consists of a high-strength steel bolt that is inserted into a hole drilled into the rock, and a split tube that is fitted over the bolt and expanded to create a tight fit between the bolt and the rock. This creates a load transfer mechanism that helps to distribute the weight of the overlying rock and prevent it from collapsing onto the mine workings below.

To use the split set stabilizer for mine support, the following steps should be taken:

1.     Determine the required length and diameter of the stabilizer: The length and diameter of the stabilizer will depend on the size and shape of the excavation, as well as the strength of the surrounding rock mass. A qualified engineer should be consulted to determine the appropriate size of the stabilizer.

2.     Drill the hole for the stabilizer: The hole for the stabilizer should be drilled using a drilling rig or hand-held drill. The hole should be drilled to the required length and diameter, and should be cleaned of any debris or loose rock. 39mm split set for sale

3.     Insert the stabilizer bolt: The stabilizer bolt should be inserted into the hole, with the threaded end facing outwards. The bolt should be inserted as far as possible into the hole, and the end of the bolt should be flush with the surface of the rock.

4.     Install the split tube: The split tube should be slid over the end of the stabilizer bolt and positioned so that it is centered over the hole. The tube should be split along its length and expanded using a mechanical or hydraulic device to create a tight fit between the tube and the rock. 39mm split set for sale

5.     Tighten the bolt: The bolt should be tightened using a torque wrench to the recommended torque specified by the manufacturer. This will ensure that the stabilizer is securely anchored in the rock mass.

6.     Repeat for additional stabilizers: If multiple stabilizers are required, the above steps should be repeated for each stabilizer. The stabilizers should be spaced according to the design specifications to provide adequate support to the surrounding rock mass. 39mm split set for sale

It is important to note that the use of split set stabilizers for mine support should be carried out by trained and experienced personnel. Proper installation techniques should be followed to ensure that the stabilizers provide the necessary support to the rock mass. The use of split set stabilizers should also be monitored regularly to ensure that they are functioning as intended and to detect any signs of instability or failure. 39mm split set for sale

In summary, the split set stabilizer is a useful tool for providing support to the rock mass in underground mines. When used correctly, it can help to prevent rockfalls and other hazards that can pose a risk to mine workers. By following the above steps for installation and monitoring, mine operators can ensure that their mine is safe and secure for workers and equipment.
