Abstract
The paper illustrates experimental determination of the effect exerted on core removal from a pipe by the initial moisture of the core, squeeze force and impact energy. An adequate numerical model of the system “pipe — earth core” is presented to describe gradual core removal from the pipe during the principal and stages of the pipe cleaning.
