Using blasting to induce fracture networks within rock mass is one of the effective reservoir stimulation methods for low-permeability sandstone-type uranium deposits. Nonetheless, there remains a deficiency suitable theoretical investigate impact CO2+O2in situ leaching on blasting-stimulated In this work, reaction-flow numerical model based fractures was first established; second, simulations blasting-induced in six injection and two extraction well groups were performed. Finally, entire process simulated under various parameters predict effect CO2+O2 Results show that trend increasing then decreasing between peak pressure recovery rate, reaching its maximum at 1000 MPa. The deposits influenced by matrix permeability, O2 concentration, HCO3− average grade. grade are positively correlated with providing sufficient seepage space required material composition leaching. However, rate negatively because it reduces reaction time agent important ranking factors affecting concentration period 900 days > permeability concentration. This study serves as reference selecting optimizing technology during field tests.
