Abstract：In order to study the stability change law of the high slopes in the weak layer group of the open-pit after plant restoration,this article used numerical simulation to analyze the stability of the high slopes in the north slope of Fuxin Haizhou Open-pit Mine before restoration,after presser foot shaping and after planting.The results show that under the consideration of unsaturated seepage and normal water level conditions,the safety coefficients of the original slope,the pressurized foot shaped slope and the mulch planted slope increased and then decreased;the safety coefficient of the mulch planted slope was lower than that of the pressurized foot shaped slope,and the mulch planted slope affected the slope stability of the open-pit slope.
