【 摘 要 】

Condition and process change modeling of chemical composition of liquid drilling wastes has been performed in waste pits located in the boggy areas of Western Siberia. Dissolved substance migration and waste water saturation indexes were calculated in relation to a number of minerals and organic-mineral compounds. It was shown that reclamation of disturbed land can be made with the use of substrate produced by mixing liquid drilling wastes, high-bog (mostly at a technical stage) and low-bog (for forest reclamation) peats.
