Description

Technical Field

[0001] The present invention relates to the technical field of mining support simulation, and in particular to an intelligent automatic similarity simulation device and method for mining support. Background Art

[0002] In the study of mining and support, similarity simulation technology is widely used to simulate the mechanical behavior in the mining process, especially in the simulation of the dynamic response and crack evolution of the mining support system. Traditional similarity simulation mining methods and support structures usually rely on manual operation and empirical judgment, which makes it difficult to achieve precise control of the experimental process. In the similarity simulation mining process, factors such as the stress state and crack development of the mine need to be monitored and adjusted in real time, but the existing technology does not fully consider the dynamic changes in the mining process during the simulation process, especially in terms of crack evolution and pressure changes, and lacks the ability to respond in real time. In addition, traditional similarity simulation support structures are usually fixed structures and cannot be adjusted in real time according to dynamic changes in the mining process, which affects the accuracy of the simulation results and the experimental effect.

[0003] At present, most of the existing similar simulated crack monitoring and support monitoring systems rely on traditional sensors and manual records. Mining, support, monitoring and dynamic adjustment devices usually work independently. This decentralized technical architecture leads to low equipment efficiency and complex overall operation, making it difficult to meet the real-time and high-efficiency requirements in complex mining environments.
