A coal measures fault formation simulation experimental device and a normal and reverse fault simulation experiment method relate to the field of similar material simulation experiment technology. The device includes a hydraulic lifting apparatus, a lower angle adjusting apparatus, a push rod apparatus, an upper loading apparatus, an upper angle adjusting apparatus, a lateral loading apparatus and a transparent side plate. The hydraulic lifting apparatus and the lower angle adjusting apparatus are below the experimental body, the upper loading apparatus and the upper angle adjusting apparatus are above the experimental body, the transparent side plate is disposed at a rear side surface of the experimental body, and the lateral loading apparatus is disposed at an end face of the experimental body. When the normal fault is simulated with the device, the inclination angle of an inclined plate of the lower angle adjusting apparatus is same as that of an inclined push plate of the upper angle adjusting apparatus, the upper loading apparatus loads downward to form a normal fault.

Provided are a normal fault simulation experiment device with an adjustable angle and an adjustable fracture initiation position and a method of using the same, which relate to the technical field of normal fault simulation experiments. The device includes a base, a column, a baffle plate, a hydraulic lifting apparatus, a lower angle adjusting apparatus, a push rod apparatus, an upper loading apparatus, an upper angle adjusting apparatus, a front baffle plate and a transparent side plate. The hydraulic lifting apparatus and the lower angle adjusting apparatus are disposed below an experimental body, the upper loading apparatus and the upper angle adjusting apparatus are disposed above the experimental body, the transparent side plate is disposed on a rear side surface of the experimental body, and a plurality of strip-shaped front baffle plates are disposed on a front side surface of the experimental body. When a normal fault is simulated by using the device, an inclined plate of the lower angle adjusting apparatus and an inclined push plate of the upper angle adjusting apparatus are at the same inclination angle, and the upper loading apparatus loads downward to form the normal fault. The technical problems that a non-practical mechanical formation mechanism is formed due to a single condition during simulation of the normal fault and the dip angle and the fracture initiation position of the fault are inconveniently adjusted are solved, bringing simple operation.
