Abstract
We give the results of experimental studies of the destruction of plaster and coal-cement blocks by pulsating jets of water and water solutions of water-soluble solid polymer compounds on a base of polyethylene oxide. It is shown that the use of water-soluble solid polymer solutions as the working fluid in the generator of the pulsating jet leads to an increase in the depth of the holes and grooves by a factor of 1.5–3.5. Three figures. One table.
