On November 3, various kinds of ores displayed at the exhibition attracted many participants.On the same day, 2023 (15th) China International Mining Conference opened in Tianjin Meijiang Convention and Exhibition Center, the conference to "opportunities, challenges, development" as the theme, around the global situation of mineral exploration, the international mineral market, mining and financial capital market, sustainable development of the mining industry, geological prospecting and scientific and technological innovation, mineral resources saving and comprehensive utilization, g

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

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.

Successful Competition for Management and Auxiliary Positions at Ruiyu Company in 2024From August 26th to 29th, 2024, Ruiyu Company carried out open competition for 15 positions of production technology, 13 positions of operation management and 5 positions of logistic service, with a total of 39 people applying for participation.The competition was divided into three stages: public opinion assessment, professional examination, and competition defense, and the results of each stage accounted for 20%, 30% and 50% of the total score respectively.Public opinion assessment by the company does not p

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.

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.

Recently, our company has newly developed a new type of support material, and the effect is obvious after use."Now there is a new type of support material, so that coal mines use lighter and more durable support, both to save production costs, but also to reduce the labor intensity of workers, the cost savings can be used for more innovative investment." A mine digging work area technician Li Ming said.It is reported that the new support material is an ultra-high strength support network.

In order to effectively improve the level of job skills of the company's employees and vigorously promote the smooth development of job training activities, the company carried out a job skills competition on November 28 in the anchoring agent workshop.The skills competition is divided into twisting tube, anchoring agent filling, cement filling three major projects, take the way of practical operation, the requirements of the specified time to complete the largest number of players and quality qualified for the first place in this project competition.
