METHOD FOR RECYCLING OF MINES AND WELLS CONSTRUCTION WASTES Russian patent published in 2010 - IPC B09B3/00 B28C5/00 C04B26/26 C04B111/20 

FIELD: technological processes.

SUBSTANCE: invention relates to methods for processing and recycling of mines and wells wastes and may find application in oil-producing and oil-processing industry, in construction of roads and arrangement of multiple well platforms. In method for recycling of mines and wells construction wastes, wastes produced as a result of drilling works - drilled rock-sludge, spent process liquor and drain drilling water are mixed for 3-5 minutes with additives - local construction material - loam or sand, dehydrator - peat, mineral wool, slag wool, cellulose fibres, silica gel, foam insulation rolled material, structure shaper - carboxymethylcellulose and/or PVAC, accelerator - technical calcium and/or sodium chloride. Produced mix is mixed for 5-10 minutes with hardener- cement and/or bitumen to make plastic-viscous homogeneous mass, moulding is carried out, as well as forming strong structure to make construction items.

EFFECT: production of construction material from wastes with elimination of migration of substances that pollute environment, convenience of this material transportation, its storage and application.
