FIELD: drilling of soil or rock.
SUBSTANCE: invention can be used in the design of buildings and structures to determine the amount of unfrozen water in frozen soils. To do this, carry out drilling with coring, thawed frozen soil sample is obtained and determine the total water content of continuous change in the course of an informative indicator of thawing. As an informative indicator of the ratio of use of acoustic emission activity of the monitored area to the array of acoustic emission activity of the most water-saturated area of the core is completely thawed; both figures take into account the specific weight of the soil and averages, consistent and comparable for the duration of the time intervals to determine the distribution of the total moisture content in depth. Registration of acoustic emission is carried out by converters to be placed on the depth of the hole array. Amount of unfrozen water in different parts of the array is calculated from the product of said index and informative total moisture content of the cores obtained at the same depth and in the same well as the corresponding value of the indicator.
EFFECT: invention provides a method of control of the geological environment.
