Abstract: The proposed concept of synthesizing the digital twin of a rock massif is based on the application of a developed method for determining stability coefficients. This method involves measuring the intensity of electromagnetic pulse (EMP) in rock formations and application of Intelligent AutoRegressive Moving Average with Bumpiness and Sparsity regularization (ARMABiS) system. ARMABiS is a modification of the Wang-Mendel fuzzy neural network designed for field processing of primary information regarding the transient process of EMP intensity before, during, and after a mass explosion in a quarry. The reconstruction of the spatial field of stability criteria for the rock massif along the quarry perimeter is also considered. The uniqueness of the method lies in the prior determination of the frequency range corresponding to the specified depth of the rock massif to assess the stability reserve coefficient. Explosions during rock blasting are used as an external influence on the massif. The method involves measuring the parameters of the transient process through electromagnetic pulse impulses during mass explosions and until the restoration of the background EMP level. The stability reserve coefficient of the massif is determined by a formula that considers the internal friction angle of rock formations, the maximum value of EMP induced by the explosion, and the duration of damping to the background EMP level
