Based on Figure 3, the strength reduction method is used to calculate the stability coefficient of the dumping step during the substrate treatment. The step parameters are shown in Table 1, and the rock mechanics parameters are shown in Table 2. In the case of j=6, that is, areas I and II are processed at the same time, calculate the k value At different times, the stability coefficient and the distribution of the stability coefficient are shown in Figure 9. After the substrate is treated, the stability coefficient increases significantly. During the increase of k, the stability coefficient increases continuously, k≥0.9, and the change of Fs decreases significantly. Tends to 1.07, fitting the points in the graph to get the following relationship
