Development’s conditions and sources of microorganisms in high-grade iron ore (HGIO)  of Jakovlevsky deposit (KMA) were considered. Influence of watering, draining and contamina  tion in iron ore on decreasing of shear strength and growth of bacterial mass were noticed. Dif ferent physiological groups and species composition of microorganisms in underground space  were defined, and their influences on constructional materials which are used to coffer mine  workings were studied.
