More Information
Summary:The invention discloses a single-free-face rock plug blasting numerical simulation inversion analysis method. The single-free-face rock plug blasting numerical simulation, inversion and analysis are carried out through establishment of an inversion analysis model, inversion analysis parameter selection and numerical simulation inversion analysis calculation. An ABAQUS/Explicit platform is adopted for establishing the inversion analysis model, including a blasting parameter primary selection test model, a blasting parameter optimization test model and a through blasting test model; inversion analysis parameter selection comprises calculation parameter selection and initial ground stress selection; the numerical simulation inversion analysis calculation comprises a blasting parameter primary selection test, a blasting parameter optimization test and a through blasting test; and finally, a kinetic energy time history is obtained in the through blasting test, and thus judging whether a sudden increasing moment in
