Zusammenfassung:	FIELD: geology; drilling practice; mining industry. SUBSTANCE: grouting material comprises Portland cement and slag as mineral additive. In its turn, Portland cement comprises Portland cement clinker and gypsum. As mineral additive, material uses crushed slag resulting from nickel production, said components are taken in the following ratio, wt.-%: Portland cement clinker, 76-80; gypsum, 4-5; crushed nickel slag, 15-20. EFFECT: reliable sealing of space around and behind drill pipe string; thermal stability for prolonged period; extended service life of bore hole support and increased production capacity. 1 tbl
