摘要
FIELD: transportation.;SUBSTANCE: method involves the implementation of thermal electric drilling of wells in ice. Simultaneously with the drilling, melt water is sucked from the edge of the working part of the heating crown, which is fed through the hose to the ice surface to the salinity meter, and the drilling speed and salinity of the melt water are recorded on the computer or logger. In further processing of the records the drilling speed is compared with the salinity of melt water, taking into account the time of water passing from the well through the hose to the salinity meter. And the drilling speed, corresponding to the transition of a drill rod from dense ice to lose ice or void and which is the closest to the sharp increase in the salinity of water drained due to the large differences in salinity of melt ice and sea water, increases, is determined as the drill rod coming out of the consolidated layer and the depth of location of its lower boundary is recorded.;EFFECT: creation of a method for determining the location of the lower boundary of the consolidated layer.;1 cl
