The article presents a description of the methodology for obtaining data on the physical properties of rocks that compose the sides of the open pit for technological optimization of drilling and blasting operations. The methodology is based on field measurements and calculation methods for determining the hardness of rocks at a chrysotile asbestos deposit, which is being mined by an open pit. The physical properties are obtained by comparing a priori geological data with the values of electrical resistivity and the velocities of elastic waves in the rocks. Based on these data, the values of the Young’s modulus are calculated, which characterizes the strength of the rocks composing the array.
