Description

Technical Field

[0001] The present invention relates to the technical field of rock and mineral mining, and in particular to a method and system for measuring the spatial relationship perception particle size distribution characteristics of blocky rock and minerals. Background Art

[0002] Due to the needs of transportation planning, energy drilling and mineral mining, people are increasingly dependent on underground resources; for example, tunnels are dug underground in cities to build subway systems to improve urban traffic conditions; underground energy materials such as oil and natural gas are explored, and various ores are mined as raw materials for industrial production. However, the existence of various rocks in the underground space, such as granite, limestone, shale, sandstone and bedrock, brings difficulties to the development of underground resources, resulting in low development efficiency and high costs.

[0003] To address the interference of underground rock and improve the efficiency of underground resource development, large-scale mining equipment such as tunnel boring machines (TBMs) have been developed. During operation, TBMs use high-strength cutting tools to cut rock and soil, and transport the cut material to the rear via a conveyor. This effectively addresses rock interference and improves the efficiency of underground resource development. However, TBMs also face safety threats during operation. Changes in the rock, such as changes in hardness, cracks, and collapses, can easily damage the TBMs.

[0004] Due to the complex design and many components of the tunnel boring machine, its construction and maintenance costs are high. Once damage or failure occurs, it will cause huge losses. Therefore, during the operation of the tunnel boring machine, it is necessary to identify and warn of abnormalities in the operation process.

[0005] Existing technologies for rock mining equipment research mainly use the mining equipment's own parameters during operation to provide early warnings, which can identify dangerous conditions to a certain extent. However, this method fails to incorporate the characteristics of rock minerals and cannot accurately identify abnormal rock changes, resulting in inaccurate warnings.

[0006] Therefore, a method and system for measuring the particle size distribution characteristics of bulk rock minerals based on spatial relationship perception is proposed. Summary of the Invention
