Abstract. The subject of research is flow of paste-like pulp along the slope of waste storage. The purpose of research is determination of distance of shift of the pulp front along the slope of waste storage and of storing cleaning rejects mass. Spreading of paste-like pulp along the slope of waste storage was simulated by creeping flow of Bengham-Shvedov medium. Differential equation describing bed height change was solved by Runge-Kutta-Felberg numerical method of 4-5^th order. The relation between Bengham number and geometric complex, which ensures pulp front shift to given distance, first was obtained. The length and angle of inclination of the slope of waste storage as well as initial pulp bed height were taken into account by geometric complex. Obtained results are planned to use during elaboration of prospective technologies of transportation and stocking of cleaning rejects in the form of paste.

Keywords:

 cleaning rejects, paste, distributed delivery, flow, slope of waste storage, cleaning rejects mass.
