Underground Mining Rock Anchor Bolt Split Set Anchor Anchor Rod:
There is no fixed standard for the hardness of the bolt, because it depends on the material and design of the bolt. The material of the bolt can include steel, wood, concrete, etc., and different materials and structural design will affect the hardness and strength of the bolt. For example, steel bar or wire rope mortar anchors will be relatively hard because they use high-strength steel as the main body.
The role of bolt:
Anchor rod plays a very important role in underground mining. First of all, it is a kind of rod system structure reinforced by rock and soil mass. Through the longitudinal tension of the bolt body, the shortcomings of the tensile capacity of rock and soil mass are far lower than the compressive capacity can be overcome. Secondly, the anchor bolt can bind the rock and soil body together and increase its cohesiveness, thus improving the overall bearing capacity of the rock and soil body. In underground mining mines, bolt is the most basic component of roadway support, which can make the surrounding rock support itself and reduce the risk of collapse and caving.
Usage scenario of bolt:
The use of bolt is very wide, not limited to underground mining. In construction engineering, bolt is usually used to strengthen the foundation and support the foundation structure to increase the bearing capacity and stability of the foundation. In geological engineering, bolt can be used to strengthen rock and soil, especially in the process of tunnel excavation and underground mine mining, the reinforcement role of bolt is particularly important. In addition, in traffic engineering, bolt is also often used to strengthen Bridges and tunnels and other structures to improve the stability and safety of the structure.
As for the disassembly and installation of bolt, this usually involves professional engineering technology and equipment. When removing the anchor bolt, it is necessary to ensure the stability of the surrounding environment and take appropriate measures to prevent the collapse or caving of the rock and soil mass. When installing a new bolt, it is necessary to select the appropriate bolt type and specification according to the specific use scenario and requirements, and carry out strict installation and fixing to ensure its stability and reliability.
