A mine rock burst prevention and control support mechanism

Abstract

The present invention discloses a support mechanism for preventing and controlling impact ground pressure in a mine. An impact-resistant buffer seat is connected to the top end of a side support seat and the other end of the support top plate. The provision of the impact-resistant buffer seat can effectively improve the impact-resistant buffering capacity of the entire support device. A buffer support mechanism is also connected between the middle and upper part of the side support seat and the middle and upper part of the main frame seat. The buffer support mechanism can provide elastic buffering force between the side support seat and the main frame seat to ensure the ability to resist impact ground pressure. The hinge point between the impact-resistant buffer seat and the support top plate is a first hinge point, and the hinge point between the impact-resistant buffer seat and the side support seat is a second hinge point. The distance between the first hinge point and the second hinge point in the vertical direction is less than 1.2 times the thickness of the support top plate in the vertical direction, which can effectively ensure that the buffering stroke and angle of the impact-resistant buffer seat are not too large, thereby effectively ensuring the buffering support effect.
