Shandong Ruiyu Company Solidly Carries Out “Safety Production Month” ActivitiesRuiyu Company closely follows the theme of “Strengthening Red Line Awareness and Promoting Safe Development”, increases safety publicity and education, strengthens the awareness of “red line”, and strictly abides by the “bottom line”.

Anchor rod main use and composition of the anchor must have factorsTwist anchor rod is mainly used in mine roadway, railroad, slope and tunnel projects, the main reinforcement of the dam, its role is mainly to ensure the stability of the mine roadway and underground engineering surrounding rock.

Application of Mining AnchorMining anchor rod is a tool applied to support the surrounding rock of mine roadway and underground project, which can ensure the stability of the surrounding rock of mine roadway and underground project.Mining anchor rod use scope, can realize end anchor, lengthening anchor and ** anchor; easy to operate, low price and other advantages, widely used in coal mines, railroads, hydropower and other projects all kinds of roadway support.Anchor is the basic component of tunnel support in contemporary coal mines, he will be the roadway rock reinforcement together, so that

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

Prestressed anchor flexible support technology and its applicationDeep foundation pit support technology has always been a popular and difficult point of concern in the academic and engineering circles.

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 ℃.

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.
