What is the anchor beam system of anchor rods?At present, in the production mines of various companies in China, some of the mining depth has reached more than 500-1000 meters, and the ground stress, surrounding rock force and deformation are complicated and diverse, a single anchor support can no longer meet the requirements of support for the broken roof plate, composite roof plate, and the roadway with high roof plate pressure, and the anchor beam system, which is composed of the anchor rods and the W-beam steel belt, can effectively control the roof plate, and it can be used in the support

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.

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.

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 ℃.

 Ultra-Deep Coal Mining Vertical Shaft To Crack The Support Problem  A few days ago, a group company improved the design of cyclic step of over-head support, which solved the problems of roof crushing caused by repeated support.

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.

Striving hard to show the style and drumming up energy to create good resultsOn April 8, the group company held a commendation meeting for the 2024 Staff Skills Competition, and commended the winning units and individuals of the skills competition, and all the six contestants selected by Ruiyu Workshop won the awards.
