We perform a systematic analysis of the mass and strong decays $\mathrm{\ensuremath{\Omega}}(2012)$ resonance in coupled-channel approach bare three-quark state composite meson-baryon state. Besides coupling ${\mathrm{\ensuremath{\Xi}}}^{*}\overline{K}$ channel, effective interactions are also included. find pole with 2008 MeV by solving Bethe-Salpeter equation. The calculated decay widths its ratios branching fractions ${\mathcal{R}}_{\mathrm{\ensuremath{\Xi}}\overline{K}}^{\mathrm{\ensuremath{\Xi}}\ensuremath{\pi}\overline{K}}$ agree well new experimental measurement Belle Collaboration. Our results suggest that both core channel essential for description resonance. expect present calculations can help us to better understand nature
