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.

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.

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 ℃.

33mm Split Tube Seam Anchor AdvantagesAs a kind of rock support equipment used in underground mining and civil engineering projects, 33 mm pipe seam anchor shows many advantages in engineering practice. First of all, its high load-bearing capacity is one of the main features of this anchor.
