The notion of unconfirmed measurement was used to develop an evaluation model of slope instability in open pit mines. To establish an evaluation system, construct a linear measurement function, and determine the weights of each evaluation indicator using an objective assignment method, nine indicators from three categories, namely geological structure, hydrogeology, rock structure, slope height, slope angle, angle of internal friction, vibration velocity of blasting mass, seismic intensity, and average annual rainfall, are chosen based on the importance of the causes affecting slope stability. The engineering application demonstrates that the evaluation model has a specific reference value for open pit mine slope stability analysis and mine safety management.
