The invention belongs to a support facility for mining security and particularly relates to a fast wave eliminating/energy dissipating/cushioning device for mining. The device comprises an upper rigid sleeve (1) and a lower rigid sleeve (2), wherein the bottom of the lower rigid sleeve (2) is fixed with an external bottom cover (6) through threaded connection, the lower rigid sleeve (2) on the external bottom cover (6) is internally provided with a cylindrical compressible energy absorbing material (5), an internal rigid bottom cover (4) is mounted on the energy absorbing material (5), the upper rigid sleeve (1) is arranged on the internal rigid bottom cover (4) through threaded connection, four pin clamps (3) with the same shape are mounted on the lower rigid sleeve (2) in a clamping manner, the internal surface of a circular ring is provided with a trapezoidal boss (3-3), and the trapezoidal boss (3-3) is embedded in a trapezoidal groove (1-1) in the external wall of the upper rigidsleeve (1). Thus, the fast wave eliminating/energy dissipating/cushioning device for mining can avoid damage of mechanical production facilities and casualty accidents of working personnel to the greatest extent.
