Split Set Rock Bolt for Coal Mining - Technical Features

1.High strength alloy strip steel is used to ensure the strength and durability of the bolt.

2.Easy installation, no need to use anchoring agent, simplifying the installation process.The friction force between bolt and rock mass is large, has high shear and tensile strength.Equipped with high strength pallet, the pallet is stressed evenly, which is conducive to dispersing stress and protecting rock mass.

3.The height of roadway is greater than the length of bolt, which ADAPTS to different construction environment.

Application features :

1.The supporting effect is good, which can mobilize and utilize the stability of surrounding rock itself, effectively control the deformation of surrounding rock, and protect the stability of surrounding rock.

2.The labor intensity is low and the efficiency is relatively high, which reduces the : transportation amount of supporting materials and reduces the labor intensity.

3.The economic benefit is more obvious, can reduce the support material input, reduce the direct support cost, and save a lot of materials.

4.The technical performance of pipe joint anchor bolt is superior, which has higher initial anchoring force, pipe ring pulling load and bolt pipe tensile breaking energy.
