Description

Technical Field

[0001] The utility model relates to the technical field of mine pressure detection equipment, in particular to a dynamic detection and prompting device for coal mine pressure. Background Art

[0002] The underground pressure monitoring system of coal mines is the basic infrastructure of coal mine information management. It is mainly used for coal mining face mine pressure observation and tunnel mine pressure observation to reduce coal mine production accidents and ensure the safe operation of mine production. The prevention and control of coal mine roof accidents mainly involves mine pressure monitoring.

[0003] The existing referenceable Chinese utility model patent has a publication number of CN219366115U, which discloses a coal mine pressure monitoring device, including a mine pressure monitor, a bracket is installed on the upper end of the mine pressure monitor, an injection frame is rotatably installed on the head of the bracket, an electric telescopic rod for driving the angle of the injection frame is installed on the bracket, and a fan is also provided at the rear end of the mine pressure monitor, and an air duct connected to the injection frame is installed at the air outlet of the fan. The utility model has the advantage of real-time cleaning of the mine pressure monitor, and the angle of the injection frame can be adjusted by the electric telescopic rod during the cleaning process, which is convenient for more comprehensive cleaning of the mine pressure monitor, avoiding the situation where dust blocks the mine pressure monitor display screen and affects observation, and can also achieve the purpose of increasing the service life of the mine pressure monitor.

[0004] The existing dynamic mine pressure detection device generally connects the lower end of the pressure sensor to the ground of the mine tunnel through a supporting structure, and the top of the pressure sensor is connected to the roof of the mine tunnel. The pressure exerted on the roof by the earth at the top of the tunnel will be transmitted to the pressure sensor, and the pressure on the roof is monitored by the pressure sensor. In order to avoid deviations between the pressure sensor monitoring data and the actual data, this method requires the support device to be kept in a vertical state during installation. The existing dynamic mine pressure detection device is very cumbersome to adjust during installation. At the same time, the overall length of the existing mine pressure detection device is fixed, and it cannot be adjusted according to the actual height of the mine tunnel, and its scope of application is small.
