Purpose - to increase the efficiency of the blast hole charges in the destruction of rocks by improving the structures of cylindrical explosive charges. Methods of research - theoretical and experimental. To achieve this aim, there are the following activities: - Analysis of advanced mathematical models for the calculation of the stress state of the environment in the explosion; - Development of a mathematical model to estimate the stress in a solid medium depending on the spatial location and the number of points to initiate a cylindrical explosive charge; - The establishment of the patterns changing of the stress in the explosion hole charges, depending on the spatial arrangement of the militants in the well; - Theoretical study of the influence of the spatial displacement of the points of initiation hole charges for changes in the destruction layers of the array; - Establishment of new geometric parameters of the spatial arrangement of the militants in the bottom of the well, which could provide the efficiency of explosive destruction of the environment; - Theoretical studies of the effect size and shape of the initiators to change the state of stress in the explosion protection; - Laboratory and industrial research of the effectiveness of the proposed schemes of initiation hole charges Product Description popup.authors Воробйов А.В.
