Using of underground space and fundamental problems of preservation environments living of men

Trends in works related to problems on assimilation of the underground space as the medium for the Earth population future environment are considered. Three basic trends are separated: 1) geomechanical provision of works relative to underground space assimilation: 2) creation of underground objects with the long-term operation for disposal of radioactive wastes disposal from the nuclear energy and modern chemical production enterprises, as well as for location of underground power plants, enrichment facilities and other production enterprises; 3) assimilation of underground space in large cities. Geomechanical provision envisages evaluation of the massif block structure, creation of geomechanic monitoring system, site selection for mining enterprises and large-sized objects with an account of geodynamic perspective, especially in places intended for construction of underground NPPs and disposal of nuclear power and other highly-toxic wastes
