This article proposes a comprehensive evaluation method for the stability of open-pit mining slope based on finite element method. Taking a certain open-pit mining site as the research object, a geometric model of the slope was constructed, reasonable rock and soil mechanics parameters were selected, and the stress, displacement, and safety factor of the slope were numerically simulated and analyzed using finite element method. Under various load combinations, the safety factor of the slope was calculated and the instability modes of different profiles were identified. The research results indicate that this method can accurately reflect the mechanical behavior of slopes under self weight, blasting vibration, and seismic loads, which helps to improve the safety and operational efficiency of mining sites.
