FIELD: mining.
SUBSTANCE: according to the method, a casing string with temperature sensors attached to its outer surface is lowered to a well and cement is pumped to an annular gap between the casing string and well walls. During a cement filling and hardening process, temperature measurements are made and thermal conductivity of surrounding mine rocks of the well is determined as per the measured relationship between temperature and time.
EFFECT: possibility of simultaneous reception of information on properties of a relatively thick layer of rocks around the well and information on thermal conductivity of rocks for the whole cemented interval of depths.
