Abstract

The invention discloses a coal series fault formation simulation test device and a forward and reverse fault simulation test method. The invention relates to the technical field of similar material simulation tests. The device comprises a hydraulic lifting device, a lower angle adjusting device, a push rod device, an upper loading device, an upper angle adjusting device, a lateral loading device and a transparent side plate, the hydraulic lifting device and the angle adjusting mechanism are arranged below the experiment body, the upper loading device and the upper angle adjusting device are arranged above the experiment body, the transparent side plate is arranged on the rear side face of the experiment body, and the lateral loading device is arranged on the end face of the experiment body. When the device is used for simulating the normal fault, the inclination angle of the inclined plate of the lower angle adjusting device is the same as that of the inclined push plate of the upper angle adjusting device, and the upper loading system loads downwards to form the normal fault; when the reverse fault is simulated, a fault inducing device is arranged at the bottom of the experimentalbody, and the reverse fault is formed through loading of a lateral loading device. The technical problem that the fault inclination angle and the crack initiation position of the simulated fault areinconvenient to control is solved.
