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 ℃.

Ruiyu Company Held a Lecture on Rebar Anchor and Mining Anchor BoltsIn order to further promote the in-depth development of the activity of “Year of Improving the Grassroots Basis of Safety Production”, enhance the awareness of life safety of the whole staff, and create a strong safety propaganda atmosphere, Ruiyu held a speech contest with the theme of “Fear of Life, Safe Development, Starting from Me” on the morning of Nov. 26th. On the morning of Nov. 26, Ruiyu Company held a speech contest with the theme of “Respect Life, Safe Development, Starting from Me”.

Principle analysis of the collapse reduction effect of left-handed anchorsIf the unstable rock layer of the vault is regarded as the combined beam (plate) supported by the side wall, because the anchor hanging on the stable surrounding rock can be regarded as the fulcrum, the installation of left-handed anchor without longitudinal ribs is equivalent to adding the fulcrum, reducing the support span, and then reducing the bending stress and deflection of the support to maintain the stability of the support and the rock, so that the rock is not easy to deform and damage.

Promote the greening of the manufacturing industryBy 2030, the output value of green factories at all levels will account for more than 40% of the total output value of the manufacturing industry; by 2030, the recycling volume of major renewable resources will reach 510 million tons, and the comprehensive utilization rate of bulk industrial solid wastes will reach 62% ......

The anchoring force test method of left-handed longitudinal ribless anchorsLeft-handed anchor without longitudinal rib has high strength, reasonable structure, large pre-tensioning force, can automatically adjust the direction of force, increase the binding force on the surrounding rock, and can realize mechanized rapid installation.Advantages of left-handed anchor:High strength anchor, reasonable structure, large preload, can automatically adjust the direction of force, increase the binding force on the surrounding rock, can realize the mechanization of rapid installation.

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.
