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

Continuously promoting new energy strategyIn 2023, the national coke production will be 50.693 million tons, an increase of 12.9 times compared to 2000; coal-to-gas will be 3.16 billion cubic meters, an increase of 9.1 times compared to 2016; compared to 2019, coal-to-naphtha will grow by 1.5 times, coal-to-diesel fuel will grow by 45.0%, coal-to-jet fuel will grow by 7.1 times, coal-to-paraffin will grow by 19.2%, and other coal-to-oil products will grow by 30.4%.The company is the first in China to innovate a new energy market-oriented consumption model and promote the implementation of six

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.

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.

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”.

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.

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.

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
