[0002] The mining industry refers to the mining of naturally occurring minerals such as solids, liquids or gases. Metal minerals refer to minerals from which certain metal elements or compounds for industrial use are extracted. During the mining process, the environment is harsh, which affects the progress of mining. When mining metal mines, it is necessary to use a ground pressure detection device. It mainly monitors the changes in internal stress of rock strata under the mine, the loosening and separation of the tunnel roof and surrounding rock, the movement amount and speed of the top and bottom plates, and other parameters. According to the monitoring data, the changes in internal stress of the rock mass, changes in the inner layer of the surrounding rock, changes in the movement amount of the top and bottom plates, curves are compiled and drawn to predict and forecast the changes in the support pressure in the rock mass, analyze and predict the future trend of ground pressure, and provide a scientific basis for formulating preventive measures and treatment plans for ground pressure, which can effectively reduce the hazards caused by ground pressure.
