This article presents the practical implementation of one of the methods for determining the disturbance coefficient of a rock mass. The essence of the method is to measure the velocity of the longitudinal wave in the rock mass and calculate the coefficient by the ratio of the velocity value obtained under field conditions to the reference value of a specific type of rock.
