UNIVERSAL METHOD OF COMPLEX WELL-DRILLING WASTE NEUTRALIZATION TO PRODUCE ANTHROPOGENIC REINFORCED SOIL (ARS) BUILDING COMPOSITE Russian patent published in 2017 - IPC C04B18/04 B09B3/00 

FIELD: mining.

SUBSTANCE: invention relates to methods of drilling waste neutralization and disposal and can be used for complex waste neutralization which is generated during drilling operations such as drilling slurries (DS), drilling waste water (DWW), waste drilling muds (WDM), contaminated soils and other pre-shredded industrial and household waste. The method of complex neutralization consists of step-by-step mixing of the waste with dry bulk components, but before application of additional components drilling waste is mixed until homogeneous condition in proportions which provide 30-500% bulk humidity of the mixture, afterwards sand for construction, sandy light and silty light loam, clay are applied to the mixture at a rate of 10-40% with allowance for preservation of the predetermined mixture humidity value, then the complexing modifying additive at a rate of 8-30% and the cement at a rate of 0-30% are applied to the mixture.

EFFECT: invention provides simultaneous neutralization of several drilling waste types and immobilization of various ecotoxicants in the structure of the newly formed mineral matrix to produce a building material, simplification and cheapening of the waste neutralization and disposal.
