Abstract: Embodiments of the present disclosure relate to a method of exploiting underground resources with a negative thixotropic fluid, which induces the fault or the fracture to slip by replacing a conventional mode of injecting water with a mode of injecting the negative thixotropic fluid. According to the negative thixotropy of the injected fluid, when the fault or the fracture does not slip, viscosity of the negative thixotropic fluid is low, and the negative thixotropic fluid could flow in the fracture network. When the fault or the fracture slips, a great shear strain rate is generated, such that the viscosity of the negative thixotropic fluid is rapidly increased with the shear strain rate, to generate a great resistance force, thereby preventing the fault from further slipping.
