Abstract

Relating to the technical field of coal mine geology, the invention discloses a test device for simulating normal and reverse fault formation. The device comprises a test stand (1), an upper verticalloading apparatus (2), a left loading apparatus (3), a right loading apparatus (4), a hydraulic oil sac (5), a bearing steel plate (6), a steel block (7) and an angle adjustment apparatus (8). The test device provided by the invention is designed with the upper vertical loading apparatus, the left loading apparatus and the right loading apparatus controlled by a hydraulic servo system, realizes different horizontal force loading, and simulates horizontal stress at different depths, U-shaped push plates actually play a horizontal sealing role in simulation of similar stratum materials, and canindependently or wholly apply loads, especially can simulate the horizontal stress of regions with complex geological structure, realizes graded loading in the horizontal direction, is closer to the real effect, and realizes simulation of the formation process of normal fault and reverse fault in one equipment.

Description

technical field

[0001] The invention relates to the technical field of coal mine geology, in particular to a test device for simulating the formation of forward and reverse faults. Background technique

[0002] The fault cuts the strata and destroys its continuity and integrity, forming a fracture zone of the fault zone, which causes great differences in the stress, displacement and failure form of the surrounding rock mass. When construction is carried out near faults, especially large faults, the superposition of engineering disturbance and faults may cause the response characteristics of the rock mass near the fault to be far different from that of the intact rock mass, thereby inducing engineering disasters, such as mine earthquakes and water inrush in mining engineering , roof caving, rock burst, coal and gas outburst, etc. my country's coal mining is dominated by well workers, most of which are underground, and inevitably cross various faults. When the faults are lar...
