Popis: Explored theoretically the interaction of explosive charges in the preliminary gap formation in quarries. A methodology has been developed for conducting experimental studies of blast well contour explosions on models, which allows one to investigate crack formation on volumetric models and wave interaction using high-speed video recording of the explosion process in transparent models, as well as determine the parameters of explosion stress waves in samples of real rocks. Theoretical and laboratory researches have established that only the creation of a screening gap for the entire height of the non-working ledge allows you to get a virtually undisturbed array with a high-quality surface of the slope
