Comparison of left-handed anchors with other anchorsLeft-handed anchor is a kind of engineering structure used to support tunnels and rock bodies. Left-handed anchors are easy to make and transport, simple to construct, and can greatly improve the quality and safety of the project. This technology has been widely used in tunnel construction and coal mine support and other fields.Second, the structure of left-handed anchorLeft-hand anchor consists of steel bar, bundle rib and self-locking nut.

Pipe seam anchors in the process of usePipe seam anchors may encounter the following common problems in the process of use:1. Sinking or loosening of pipe seam anchors: sinking or loosening of anchors may occur after the anchors are subjected to loads.

Background on Hollow AnchorsTo better understand the mechanics involved in load transfer between anchors and mine rock, the Bureau of Mines initiated a program to study the load transfer mechanics of passive, fully grouted hollow anchors. This work was accomplished in support of the Bureau's goal of improving the underground safety of the nation's miners. The first phase of the study was conducted in the laboratory to examine the linear, nonlinear, and time-dependent behavior of anchor rods under varying load conditions.

Mining roadway anchors in the use of what to do before the inspectionMining anchor is the basic component of tunnel support in contemporary coal mines, which is used in the support of the surrounding rock of the mine tunnel and underground project, and can ensure the stability of the surrounding rock of the mine tunnel and underground project. It reinforces the surrounding rock of the roadway together, so that the surrounding rock supports itself.

What are the elements that affect the decrease of anchoring force of mining anchor rods?With the development of mine support technology, anchors and anchors are used in conjunction with each other. However, in the detailed underground use process, due to the quality of the anchoring material itself, irrational design, improper operation process, underground geological conditions and many other factors, the anchoring force will be greatly reduced. This will lead to deformation of the roadway, and even topping and roadway collapse accidents.

Ruiyu support takes you to understand the hollow anchor rods in the minesSince the introduction of hollow anchors 40 years ago, their use in mines has gradually increased for support and stabilization of underground mines with remarkable results. Hollow anchors have significantly reduced the number of roof falls and are now the primary support option required by most mine safety and health authorities.

Shandong Ruiyu Company Solidly Carries Out the Activities of Rule of Law Awareness MonthFrom April 1 to 22, Ruiyu Company organized and carried out rule of law publicity and education activities with the theme of “enhancing the concept of rule of law and promoting the rule of law”.Firstly, by posting cartoon version of the Constitution publicity wall charts on the bulletin boards, the company publicized the concept of supremacy of the Constitution and rule of law according to the Constitution in an easy-to-understand way, publicized the basic rights and obligations of citizens, safeguarded the

Anchor rods are a type of support equipment commonly used in civil engineering and mining projects to enhance the stability and safety of underground structures. Here are some key points about the development trend of anchor rods:Advances in material technology: with the continuous development of material technology, the application of new materials is changing the performance and reliability of anchor rods.

The role of contemporary anchorMining anchor is the basic component of tunnel support in contemporary coal mines, which reinforces the surrounding rock of the tunnel together and makes the surrounding rock support itself. Nowadays, anchors are not only used in mines, but also used in engineering technology to reinforce the main body of slopes, tunnels and dams.

Factors affecting the quality of anchor tray determinations(1) Environmental temperature change, due to thermal expansion, the balance of the unequal arm and other reasons, will make the balance of the zero point and the equilibrium point of change, the value of the occasional deviation can be up to a number of times the balance of the sensibility. Thus, the balance room should be a constant temperature, first-class, second-class standard balance and first and second-class laboratory balance should be 20 ℃ ± 2 ℃ under the conditions of work, the accuracy of a little lower to reach 20 ℃ ± 5 ℃.
