“…To verify the validity and applicability of the proposed EFAHP-SPA model, the fuzzy comprehensive evaluation method [18,19] and the entropy-SPA model [4] were used to evaluate the stability of four sample slopes in the study area, respectively, and the calculation results of the three methods were compared and analyzed. To facilitate the comparative analysis, the weight of fuzzy comprehensive evaluation method is calculated using the subjective weight determined in this paper.…”

“…To facilitate the comparative analysis, the weight of fuzzy comprehensive evaluation method is calculated using the subjective weight determined in this paper. In addition, when judging the slope stability grade, the fuzzy comprehensive evaluation method uses the conventional maximum membership principle to judge the stability [18], while the entropy-SPA model uses the confidence criterion to judge the stability grade. e results of slope stability evaluation by these two methods are shown in Tables 10 and 11.…”

“…Referring to the relevant specifications of open-pit slope design and a large number of literature [7,18,42], and combined with the geological survey data of the open-pit slope engineering, this paper constructs the open-pit slope stability evaluation index system, as show in Figure 3. e comprehensive evaluation index system is mainly composed of a primary evaluation subsystem composed of topography and landforms, engineering geological characteristics, meteorological and hydrological characteristics and other factors, as well as several secondary subsystems subdivided by each subsystem, as shown in Table 2.…”

“…For this reason, many experts and scholars have put forward the multi-index evaluation models of slope stability combining qualitative and quantitative in recent years, such as fuzzy comprehensive evaluation [18,19], analytic hierarchy process (AHP) [20], Topsis theory [21,22], artificial neural networks (ANNs) [23,24], and extension method [25,26]. Although the aforementioned research results have made great progress, there are still some limitations due to the different emphasis of various evaluation methods.…”

In this paper, combined with fuzzy analytic hierarchy process (FAHP), information entropy theory, and set pair analysis (SPA) theory, an improved set pair analysis model (EFAHP-SPA) for open-pit mine slope stability evaluation based on entropy method and FAHP is proposed. Taking the east-side slope of Tonglvshan north open-pit mine in Daye as an example, the proposed method is verified. First, an open-pit mine slope stability evaluation index system with 14 indicators in 4 categories, namely the topography and geomorphology, geological structure, hydrogeology, and other factors, have been constructed. Second, the objective weight and subjective weight of each evaluation index are calculated by entropy and fuzzy analytic hierarchy process, and then the comprehensive weight of the evaluation index is estimated based on subjective weight and objective weight. Afterward, the single-index connection degree between the evaluation index and the evaluation standard of the secondary subsystem is evaluated considering the improved set pair analysis theory, and the comprehensive connection degree of the system is obtained by combining it with the comprehensive weight of each evaluation index. Finally, the confidence criterion is established to discern the risk grade of slope stability in the east-side slope of the north open pit in Daye Tonglvshan mine. Moreover, case studies and comparisons of the proposed model with fuzzy comprehensive evaluation method and Entropy-SPA model were performed to confirm the validity and reliability. The results show that the evaluation results of the proposed EFAHP-SPA model are consistent with the actual situation of open-pit mines and the evaluation results of entropy-SPA model and are somewhat different from those of fuzzy comprehensive evaluation method. It indicates that the proposed EFAHP-SPA evaluation model can objectively evaluate the slope stability of the open-pit mine.

“…Since there are many factors affecting slope stability, no matter what method is used in the quantitative evaluation, all factors cannot be taken into account. Based on this, Yang et al (2016) used a fuzzy evaluation method and combined qualitative and quantitative methods to analyze the slope stability of coal mining subsidence areas. Wang et al (2020) adopted CRITIC method to obtain objective weights of slope evaluation indexes.…”

Coal mining under slopes often leads to slope instability, resulting in substantial economic losses and human casualties. Therefore, constructing a scientific and practical slope stability evaluation model for slope disaster prevention and control is of great significance. In this study, seven evaluation indexes were selected, and their influence mechanisms were analyzed to establish a system of evaluation indexes for the stability of mining slopes in Xing County, Shanxi Province, China. A new evaluation model for the stability of mining slopes was established based on the interval analytic hierarchy process (IAHP) to determine the subjective weights of the indexes and the improved CRITIC method to determine the objective weights of the indexes, which circumvented the limitations of subjective or objective weights by combining the minimum discriminating information. The model was applied to the mining slopes in Xing County, Shanxi Province, and the results showed that slopes A, C, D and E were in an unstable state, slope B was in an understable state after mining. Finally, the accuracy of the evaluation results was verified through field surveys. The model has engineering application value in predicting the stability of mining slopes and can provide theoretical suggestions for later slope management to ensure the safe production of coal mines.
