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

The main factors of integrity and stability of anchor supportThe put into use of anchor rods eliminates the hidden dangers in safety production to a certain extent and reduces the labor intensity of workers.

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 ℃.

Borehole diameter of anchor rods is related to soil conditionsWhat is the typical drilling diameter of anchor rods?Anchor bar is a common foundation reinforcement material used in construction projects. It is made by pre-burying steel bars in the soil, and then pre-stressing and mechanically drilling them, so that the steel bars are tightly bonded with the soil, thus the strength of the soil and foundation can be improved.

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.

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

October 10, Song Hongpeng, secretary of the municipal party committee, led a team to my town to observe the progress of the project in the third quarter, accompanied by party secretary Bai Zongcheng, deputy secretary of the party committee, mayor of the town, Dong Gang, on-site report on the construction of the project.

Ruiyu Company Organizes Emergency Rescue Knowledge Training In order to protect the safety of employees and pay attention to their health conditions in real time, Ruiyu Company has equipped workshops with special first-aid medicine boxes, blood pressure monitors, patchouli, quick-acting heart pills and other medical and healthcare supplies, and has established a relevant medical apparatus management system and processing procedures to facilitate the temporary rescue of employees in the event of a health emergency.

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.

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.
