Problems solved by technology

In recent years, some domestic scholars have carried out the research on the identification method of coal-gangue interface based on the vibration signal of the tail beam, and achieved very effective results. Through signal processing and feature extraction, the coal-gangue interface can be more accurately identified in the laboratory. , but there is still a big gap from the actual engineering application, and the identification method is not perfect
At the same time, due to the lack of relevant theories, the theoretical development of coal gangue identification in caving mining based on data analysis and the practical application of coal gangue identification technology are seriously restricted.
In order to clearly understand the essential cause of signal generation and the real propagation law under various field conditions, it is necessary to conduct quantitative analysis on the vibration characteristics when rock and coal impact the tail beam during the research process, but there is a lack of reasonable experimental equipment at this stage. To verify and assist research

Description

technical field [0001] The invention relates to a caving coal gangue impact vibration test device and an application thereof, and belongs to the technical field of coal gangue interface identification in top coal caving mining. Background technique [0002] Coal plays a dominant role in my country's energy resources, is related to the development of national industry and agriculture, and plays a pivotal role in the entire national economy. The development of coal mining technology is an important measure to increase the rate of coal mining and an important means to increase coal production. At the same time, the automation of coal mining is conducive to improving the working conditions of workers, reducing personal casualties and improving labor production efficiency. Thick coal seams account for about 44.8% of my country's total coal reserves, and a considerable part of the nearly 3 billion tons of coal each year is mined by top-coal caving. Therefore, the research and pro...
