Abstract
Monitoring of the state of natural and synthesized structural elements of underground structures is a prerequisite for their safe construction and operation. Improvement of reliability and efficiency of such monitoring can be achieved by integrated use of ultrasonic and video logging methods of monitoring wells drilled in the contour zone of excavations and tunnels. For the hardware support of the mentioned methods, the specialized measuring complex was developed and implemented, which provides obtaining of the operative information about the structure, properties and state of the geological material in the vicinity of the excavated space.
