Resource-Saving Technologies of Using Ash-and-Slag Storages of Thermal Power Stations

Abstract

A problem of the further maintenance of ash-and-slag storages is sharply standing in the coal power generation in the fuel-energy complex of the Russian
Federation. In connection with this, the search of new engineering solutions in the field of permissible and environmentally safe preparation technologies of a storage
to reception of ash-and-slag pulps and levee building. The author's technologies propose trench boring by hydraulic excavators of the "reverse spade" type
with the simultaneous formation of levees. The developed technologies of maintenance of ash-and-slag storages provide a twentyfold reduction of expenses and
thirtyfold reduction of emission of pollutants when building the storage levees.
