In the field of mining, the performance of equipment directly affects production efficiency, safety and environmental protection level, as well as the economic benefits of enterprises.
In the face of the complex and changeable operating environment of different mines, YZH has constantly explored YZH’S strength static boom system innovation and improvement, and successfully overcome a series of technical problems, among which the equipment application achievements for the special scenarios such as the undersea mining of Sanshandao Gold Mine, the mining in Xizang Plateau, and calcium carbide production are particularly remarkable. At the same time, the application of YZH’S strength static boom system in different scenarios has also provided diversified solutions for mine mining.
The underwater mining operation of Sanshan Island Gold Mine is facing the challenge of severe exceeding of chloride ions.
Chloride ions have extremely strong corrosiveness, and metal components of ordinary equipment are easily corroded in this environment, leading to frequent equipment failures and high maintenance costs, seriously affecting the continuity and stability of mining operations.
To solve this problem, YZH organized a professional technical team to conduct in-depth research on the principle of chloride ion corrosion and carried out comprehensive performance improvements on the YZH’S strength static boom system.
In terms of material selection, a new type of corrosion-resistant alloy material has been used, which has undergone special processing and has excellent resistance to chloride ion corrosion;
In terms of equipment structure design, the sealing structure has been optimized, enhancing the protective performance of the YZH’S strength static boom system and effectively preventing chloride ions from corroding key components inside the YZH’S strength static boom system.
The improved YZH’S strength static boom system not only significantly extends its service life and reduces the failure rate, but also ensures the efficient and stable operation of underwater mining operations, achieving good economic and social benefits.
The specific comparison of data before and after improvement is as follows:

At the same time, in the cold area of the Xizang Plateau, 5000 meters above sea level, the equipment operation is facing the test of extreme climatic conditions.
Low temperature can increase the viscosity of lubricating oil in equipment, leading to increased resistance and even jamming of mechanical components during operation;
The thin air in high-altitude areas can affect the combustion efficiency of YZH’S strength static boom system engines and reduce equipment power.
In response to these issues, YZH has made adaptive modifications to the equipment.
The YZH’S strength static boom system is equipped with specialized lubricating oil and antifreeze with excellent low-temperature performance, ensuring that the equipment can start and operate normally in low-temperature environments;
The engine has been optimized and tuned, using a high-altitude dedicated intake system and fuel injection system to improve the power output of the engine in high-altitude areas.
At present, the equipment has been running stably for a long time under the harsh environment of the Xizang Plateau, and the use condition is good, which fully proves its excellent performance and reliability.

In the field of calcium carbide production, the severe dust pollution and harsh working environment of high temperature and high magnetism on site pose a great threat to the physical health of operators and the normal operation of equipment.
The traditional manual operation method is not only inefficient, but also has serious safety hazards.
YZH's remote control strength static boom system provides an effective solution to this problem.
This YZH’S strength static boom system adopts advanced hydraulic transmission technology and has strong crushing force, which can easily cope with the crushing of large materials in the production process of calcium carbide.
Through remote control, operators can accurately control the YZH’S strength static boom system in a safe location far from hazardous work areas, avoiding the harm of dust, high temperature, and strong magnetism to the human body, while also improving production efficiency and job safety.
In underground mining operations, the YZH’S strength static boom system jointly developed by our company and China Mining Institute has become a successful case in the construction of digital mines.
The system transmits real-time on-site images and equipment operation data to the surface central control room by installing high-definition cameras and sensors at numerous crushing points underground.
The operator can clearly observe every detail of the underground crushing operation through a large screen display in the control room, and use a professional operating handle to remotely operate the YZH’S strength static boom system.
This YZH’S strength static boom system not only achieves precise control of underground crushing operations, but also greatly reduces the number of underground workers and lowers safety risks.
Compared with traditional manual crushing and YZH’S strength static boom systems, remote video remote control underground hydraulic crushing robotic arms have higher flexibility and adaptability, and can quickly adjust the operating position and crushing method in complex and changing underground environments, significantly improving crushing efficiency.

As an important equipment in mining crushing operations, YZH’S strength static boom systems also play an irreplaceable role in specific scenarios.
It is usually installed on a fixed work platform and has the characteristics of stable structure and strong crushing force.
YZH’S strength static boom systems are suitable for mining areas with relatively stable ore production and relatively fixed operating environments.
Its working arm can rotate and extend within a certain range, crushing and processing ores in a fixed area.
Compared with remote control hydraulic crushing robotic arms, the advantages of YZH’S strength static boom systems lie in their strong continuous crushing capacity and lower operating costs.
In some large-scale open-pit mining sites, YZH’S strength static boom systems can operate continuously for a long time, crushing the mined large ore into particle sizes suitable for transportation and subsequent processing.
In addition, the maintenance of YZH’S strength static boom systems is relatively simple, requiring only regular lubrication and inspection of the joint parts of the YZH’S strength static boom system, and replacement of worn components. This gives it a certain cost advantage in equipment maintenance.
However, YZH’S strength static boom systems also have obvious limitations. Due to their fixed installation characteristics, their operating range is relatively fixed and they cannot quickly adapt to complex and changing operating environments and requirements.
When there are changes in the mining area or special geological conditions, the YZH’S strength static boom system arm needs to be reinstalled and debugged, which not only consumes time and effort, but also affects the production schedule.
Our company has achieved remarkable results in innovation and practice in the field of mining equipment, whether it is improving equipment performance for special environments or developing and applying new remote control equipment.
Meanwhile, through the rational use and analysis comparison of traditional equipment such as fixed crushing booms, more scientific and efficient equipment solutions have been provided for different mining operation scenarios.
In the future, YZH will continue to increase research and development investment, constantly explore new technologies and applications, and contribute more to promoting the intelligent and green development of the mining industry.
