FIELD : chemistry.SUBSTANCE : method of decontaminating oil-contaminated soil involves preparation of a treatment area, collecting, excavating and delivering oil-contaminated soil to the treatment area, preparing the oil-contaminated soil, adding a humic-mineral complex and providing processes for biological decomposition of the oil-contaminated soil. The method of decontaminating spent drilling mud involves lime treatment, reagent coagulation, adding flocculants and a humic-mineral complex, step-by-step cutting of the drilling mud into a buffer layer while laying the mud in a layer of not more than 8-10 cm, drying the drilling mud and stacking into piles for subsequent recycling. The humic-mineral complex is obtained by low-temperature mechanochemical extraction of humic acids with by crushing brown coal in a dispersion machine while mixing the crushed brown coal with an alkali.EFFECT : invention increases efficiency of methods in which a humic-mineral complex is used.2 cl, 2 ex
