FIELD: ice-technology.
SUBSTANCE: invention relates to ice science and ice engineering and can be used in ice research, in particular in areas of hydrocarbon production on shelf of freezing seas. During process of thermal drilling of stamukha, speed of drilling and transparency of melt water near face are recorded on computer. As soon as thermobur passes through ice into ground, its transparency will decrease dramatically. In subsequent data processing on computer, dependence of drilling speed on depth and transparency of melt water is compared. Depth at which decrease in transparency of melt water occurred, corresponding to transition of drill from ice into ground, is defined as depth of ice and soil boundary.
EFFECT: technical result is to improve accuracy of determining boundary of ice and ground during drilling.
