Description

Technical Field

[0001] This invention relates to the field of geological sequestration technology, and in particular to a numerical simulation method for geological sequestration of mine water. Background Technology

[0002] With the acceleration of China's industrialization, a continuous stream of domestic and industrial waste liquids are generated, which are difficult to treat and pose great hazards. Improper treatment can cause incalculable damage to the ecological environment and endanger people's safety. With the development of technology, deep well underground injection has become one of the important methods for the disposal of hazardous waste liquids. Selective underground injection of chemical industrial waste liquids is safer than almost all other treatment methods.

[0003] In the prior art, invention patent application number 202011591109.9 discloses a numerical simulation method for geological sequestration of mine water. This method involves collecting data parameters from different regions to select suitable areas for deep geological sequestration of hazardous waste liquids. It then establishes corresponding hydrogeological conceptual and mathematical models, imports them into software for calculation, and obtains preliminary data results. Subsequently, it simulates data under varying parameters such as viscosity, density, and hydrogeological parameters to simulate the changes in landfilled hazardous waste liquids under different data conditions. By combining these simulation results with the preliminary data, conclusions are drawn to explore the impact of hazardous waste liquid landfill on the surrounding ecological environment, thereby improving the success and variability of hazardous waste liquid landfilling. However, during application, the applicant found that the numerical simulation method for geological sequestration of mine water provided by this prior art mainly relies on conceptual and mathematical models, with theoretical basis as the primary approach. However, in practice, there are often deviations between theory and reality, which can affect the success and variability of hazardous waste liquid landfilling.
