Influence of drainage water injection in the lower carboniferous aquifer on stability of the protective aquiclude of the Yakovlevsky mine of the same-name deposit KMA (physical-chemical and biochemical aspects)

Article preview

Drainage water formation of the Yakovlevsky mine (Yakovlevsky deposit, KMA) is considered, as well as the features of its discharge to soak away and thereto related ecological issues. Ways of drainage water treatment are presented. The particular focus is given to the project of its disposal in the high-head Lower Carboniferous aquifer using injection methods. Negative effects of this measure and nature of its impact on the water-protective layer, determining safety of mining operations, are stated.

Microbial activity in mine working and its influence on high-grade iron ore's and constructional material's properties

Article preview

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.

Engiineering-geological and hydrogeological problems of st. Isaak cathedral’s long-term stability substantiation (Saint-Petersburg)

Article preview

In the paper construction specificity of St. Isaak Cathedral’s underground space and engineering geological profile features are considered. The comparative assessment of condition and properties modification of water-saturated quarternary sandy and clay soils during 55 years are taken up (1954-2009). The dynamic of groundwater contamination due to leakage sewers and its aggressiveness are estimated. The researches of microbes activity in soils which are characterized by quasiheavy values are completed. The structural  of complex monitoring to secure of St. Isaak Cathedral long-term stability are proposed.
