In order to increase the efficiency of control of permafrost degradation in the basements of the large mines in cryolithozone a new approach to monitoring of state of frozen ground is suggested. This approach is based on using of the new temperature logger automated systems. The description of the operating model of the permafrost degradation control system in the ground of basement of the engineering object is provided. The control is carried out by registering the temperature field. The components of the direct and backfeed loop of this system are defined. It is demonstrated that using of the three¬dimensional isothermal surfaces of the temperature field of the object base are optimal for detecting the thermal perculiarities of an object.
