摘要： A testing device for simulating coalbump includes a testing chamber. A first oil cylinder, a second oil cylinder and a third oil cylinder are provided within the testing chamber; each piston rod of each oil cylinder can stretch or retract. A first reaction seat, a second reaction seat and a third reaction seat are arranged opposite to a side of the first piston rod of the first oil cylinder, a side of the second piston rod of the second oil cylinder and a side of the third piston rod of the third oil cylinder respectively. The testing device includes a shear loading unit including a fourth oil cylinder and a fifth oil cylinder located on a same axis, and a side of a fourth piston rod of the fourth oil cylinder and a side of a fifth piston rod of the fifth oil cylinder are arranged opposite to each other.
