  • HIGH-FREQUENCY, POWERFUL, REPEATABLE IMPACT SEISMIC SOURCE SYSTEM AND IMPACT METHOD
    Publication number: 20260202563
    Abstract: A high-frequency, powerful, repeatable impact seismic source system includes: a barrel, provided with a firing chamber, a recovery chamber and an impact chamber connected sequentially; an impact projectile, sealingly and slidably provided within the impact chamber along an axial direction of the barrel; a firing apparatus, an air outlet end of the firing apparatus being coupled to an air inlet end of the firing chamber, the firing apparatus charges the firing chamber with gas to a predetermined pressure, and the impact projectile moves in a direction away from the recovery chamber driven by the gas; and a recovery apparatus, an air inlet end of the recovery apparatus being coupled to the air outlet end of the recovery chamber, the recovery apparatus evacuates the recovery chamber to a predetermined vacuum degree to enable the impact projectile to move in a direction close to the recovery chamber.

  • Method for detecting structural abnormal area of coal and rock mass
    Patent number: 12111437
    Abstract: A method for detecting a structural abnormal area of a coal and rock mass is provided. The method includes acquiring a target velocity inversion map of the coal and rock mass in a target detection cycle, in which the target velocity inversion map is configured to indicate a target velocity of seismic wave propagation in each of grid cells in a target detection area, acquiring a first velocity of seismic wave propagation in any one of the grid cells in at least one detection cycle preceding the target detection cycle, determining, according to each of the first velocities and the target velocities, structural abnormal cells from each of the grid cells, and determining, according to the structural abnormal cells, a range of the structural abnormal area of the coal and rock mass in the target detection cycle in the target velocity inversion map.
