The performed experimental studies made it possible to obtain the values of quantities that makes it possible to analyze and refine the mathematical model of the formation of energy consumption for ice destruction. Experimental studies were carried out using destructive elements (see Fig. 2a,b). Recording the process of crack development using high-speed photography revealed that the use of a destructive element with a straight knife of constant cross-section installed at the end (see Fig.2b) ensures rapid and stable propagation of the crack, which leads to the chipping of a volume of ice from the block. In this case, the time of elastic interaction decreases, which leads to a decrease in energy consumption for the destruction process. 4. Conclusions Experimental studies of the process of separating ice from the massif were carried out based on the results of the hypothesis about the proportionality of the volume of the stressed zone that is formed in the body of the ice block to the time of contact interaction of the destructive element with it was confirmed. Based on the experiment, it was established that to ensure a less energy-consuming process of ice destruction, wedge-shaped destructive structural elements with a straight knife of constant cross-section installed at the end should be used. The immersion depth of the destructive element changes nonlinearly when the ice thickness changes. It is explained by the increase in the conditional resistance to separating the volume of the destroyed ice. Provided that the temperature of the ice decreases by 5 ° C, for the ice to break off, the destructive element must be immersed in the block to a lesser depth, on average 11%. This leads to a decrease in the destruction energy. References Combescur, A., Chuzel-Marmot, Y., Fabis, J., 2011. Experimental study of high-velocity impact and fracture of ice.
