The invention belongs to coal mine safety production equipment, and specifically relates to a constant resistance avoiding energy-absorbing device for mining. A joint (1) is inserted in the lower end inside an energy-absorbing component sleeve (3). The lower end of the joint (1) is provided with a hollow section (1-2). The outer circumferential wall of the joint (1) at the hollow section (1-2) of the joint (1) is provided with a hoop groove (1-1). The upper end face of the joint (1) is in contact with the lower end face of a pressure head (4). The upper end of the pressure head (4) is a cylindrical body having a tapered surface (4-1). A horn mouth (5-1) of a horn-shaped energy-absorbing circular tube (5) is connected with the tapered surface (4-1) of the pressure head (4). An energy-absorbing component is constituted by the pressure head (4) and the horn-shaped energy-absorbing circular tube (5). A energy-absorbing device connecting circular top (6) is fixedly connected above the energy-absorbing component and the energy-absorbing component sleeve (3). The outer circumference of the energy-absorbing component sleeve (3) is correspondingly provided with a cylindrical pin sliding chute (3-1). The constant resistance avoiding energy-absorbing device for mining can increase the impact resistance and the earth pressure resistance of the surrounding rock support system, can effectively solve and reduce multiple times of upright column working resistance, thereby improving the impact pressure to the vertical columns.
