Ecological Systems and Devices Annotation << Back Ecological features of a split extraction in underground development of shallow veins Y.P. Galchenko M.V. Lizunkin A.S. Shuklin This paper reviewed and evaluated the environmental effects of the use of geotechnology with separate extraction in underground gently sloping low power veins. Theoretically found and experimentally confirmed the feasibility and effectiveness of the twin-contiguous charges at small angles of incidence veins. A new technique for the quantitative assessment of the environmental impacts of the separate extraction of ores and rocks in veins deposits. Key words: in parallel-connivent charges, grain size, completeness and quality of mineral extraction, experimental-industrial testing. Contacts: E-mail: LMV1972@mail.ru Pp. 69-74.
