Abstract

The problem of engineering and geological support for drilling-and- blasting operations in a frozen rock mass with underground ice reducing the blasting efficiency is considered. A survey of methods for underground ice searching is carried out and the georadiolocation method is proposed as one of the most operational and efficient. Underground ice identification criteria are developed which allow using the georadiolocation method for searching the formation ice, simplify and accelerate the georadiolocation data processing .
