STUDY OF HEAT EXCHANGE IN ISOLATED SPACE OF DREDGE OPEN CUT
The problem of decrease in productivity of dredges at work in the conditions of negative temperatures which is especially actual for the deposits located in the conditions of the Far North where the mining season is limited by climatic conditions is considered. The existing ways of prolonging the dredging season are shown, and a method for isolating the dredge open cut with modern artificial materials is proposed. An experiment was conducted to confirm the effectiveness of this method by creating an experimental setup. As the insulating material selected polycarbonate, which has a number of advantages. A mathematical model is obtained that allows to determine the temperature inside the isolated space of the dredge open cut as a function of the water temperature of the section and the surrounding air. It is proved that the application of the proposed method will allow to prolong the mining season. The distribution of thermal fields in the isolated space of the dredge open cut is also presented.
