Split set is a product widely used in coal mine underground support system. Split set is usually composed of accessories such as mine rock bolt, anchor plate, nut, etc. These accessories play an indispensable role in the use of split set.

1. The anchor plate must apply the corresponding torque to the nut, so that the anchor plate can compress the roadway surface, provide a certain pretension to the split set, and allow the pretension to spread into the coal rock body around the anchor, and then changing the stress condition of surrounding rock can well prevent the separation of surrounding rock, the sliding of structural plane and the opening of joint cracks, and finally achieve the initiative and timeliness of the split set support.

2. Deform the surrounding rock more, let the load act on the anchor plate, and rely on the anchor plate to transfer the load to the pipe body of the split set, thereby increasing the working resistance of the anchor and allowing the split set to fully control the deformation of the surrounding rock the role. Each part of the split set is an important part of the supporting system, and the product performance of the anchor plate affects the supporting effect of the anchor directly.

When choosing the anchor plate, you must pay attention to the following issues:

1. The anchor plate needs to match the strength of the split set body, as long as the strength matches to achieve a good supporting effect, otherwise the strength of the anchor plate and rock bolt will not show the problem of mine bolt penetration.

2. The anchor plate needs to meet the matching of the split set body on the supporting structure. If the rod body of the mine rock bolt and the anchor plate are not matched, the uneven stress of the mine bolt body and nut will be formed, which affects the mine roadway supporting effect directly.

Split sets play a significant role in the supporting system. This is the result of the mutual cooperation between the mine bolt body and the anchor plate nut. If you have any needs for supporting products, please contact us!
