Description

Technical Field

[0001] This utility model relates to the field of mining operation equipment technology, and in particular to a mining operation equipment suitable for confined spaces. Background Technology

[0002] In recent years, with the accelerated pace of global industrialization and the booming development of emerging industries, the demand for various mineral resources has been continuously rising. Taking the new energy field as an example, the lithium, cobalt, and nickel metal minerals required for lithium battery manufacturing, the construction of 5G communication base stations, and the rise of the chip manufacturing industry have also significantly increased the dependence on copper and rare earth mineral resources. However, after long-term large-scale mining, easily exploitable surface and shallow mineral resources have become increasingly depleted, forcing the mining industry to turn its attention to areas with more complex terrain and greater mining difficulties. At the same time, with the continuous development of artificial intelligence, new materials, and microelectromechanical systems (MEMS) technology, the traditional mining industry is facing an urgent need for transformation and upgrading. However, mining operation equipment for confined spaces is still in the research and development stage. Existing technological achievements have many shortcomings in practical applications and cannot meet the industry's urgent needs for efficient, safe, and intelligent mining. Therefore, it is urgent to develop a mining operation equipment suitable for confined spaces. It is necessary to make innovative breakthroughs in structural design, power system, intelligent control, and safety protection to promote the development of the mining industry towards refinement and intelligence.

[0003] Currently, mining equipment on the market mainly consists of a power system and a mining mechanism. Although traditional mining equipment has developed into a relatively mature system over a long period of time, it still reveals many limitations when dealing with complex and ever-changing mining environments. In large open-pit mining, traditional giant excavators and dump trucks, while possessing powerful mining and transportation capabilities, suffer from high energy consumption and pollution. Furthermore, as the mining depth increases, these devices lack flexibility when operating in narrow pits, easily leading to safety accidents. While new adjustable mining equipment on the market has solved the problem of the previous equipment being too large and inconvenient to use in confined spaces, traditional mining equipment faces even more severe challenges in underground mining. The geological structure of underground tunnels is complex and varied, often encountering faults, fracture zones, and other adverse geological conditions. When traditional tunnel boring machines encounter areas with significant differences in rock hardness, their tunneling speed fluctuates greatly due to a lack of intelligent adjustment and adaptive capabilities. When encountering harder rocks, the tunneling speed drops significantly, and problems such as severe tool wear and equipment failure can occur, seriously affecting the mining progress. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a mining operation device suitable for confined spaces, aiming to improve the problem of low efficiency of traditional mining operation devices in the prior art.
