Abstract
Under discussion is plastic soil removal in horizontal rotating pipeline by air flow. It is experimentally proved possible to remove soil by batches generated during rotation of the pipeline. The found relationship between soil conveying in the pipeline, the pipeline diameter and air forward pressure is made the basis of determining parameters of the main transporting line in a drilling installation.
