摘要
This invention relates to the coal mining field, specifically, to an integrated experimental system of hydrofracturing, water jet slotting, seepage and gas displacement under true triaxial stress. This invention consists of true triaxial stress loading experimental framework, a loading system and a monitoring system. Under true triaxial stress, experiments can be conducted with sample size as large as of 500 mm×500 mm×500 mm. The hydrofracturing experiment can be controlled by as many as 5 independent boreholes at the same time. The borehole water pressure in hydraulic fracturing can reach 63 MPa. Experiments of seepage and fluid-structure interaction with high seepage pressure can be achieved with sample dimension as large as 400 mm×400 mm×400 mm. Mine-used experimental bench of high pressure pump with rated flow of 70 L/min and maximum water pressure of 70 MPa can be used to drill borehole and the like.
