Abstract
The present disclosure relates to a hydraulic support with a quick response function for coal wall spalling, which includes a base, an upright post, a top beam, an extensible canopy, a face guard, and a vibration meter. The vibration meter is mounted on a hydraulic support, and detects a vibration signal of a coal wall in a non-contact mode. The face guard includes a primary face guard, a secondary face guard, and a tertiary face guard connected in sequence. One side, close to a coal wall, of the primary face guard is connected to a quick response device. The quick response device is in signal communication with the vibration meter. After receiving the vibration signal of the coal wall, the quick response device is abutted against the coal wall before the secondary face guard and the tertiary face guard fit the coal wall.
