The basic natural and anthropogenic reasons of accidents at subsurface use are defined. On the ground of performed researches the most effective technologies of rock massif analysis for the modern forecast and decrease of accidents at subsurface use are developed. The basic research methods of massif tectonic structure. One of the most perspective methods studying massif structure, especially in the conditions city building, deposits ore minerals, and also in underground mountain developments the geophysical method of spectral seismic profiling. The cause of the many-storied apartment house destruction constructed on the rocky basis is resulted. For revealing of the reasons of deformations massif by several methods land geophysics, including researches have been conducted in a variant of spectral seismic profiling. The geomechanical model of a site has been by results constructed, the tectonic zones crossing a building are allocated. Diagnostics methods of rock massif for safe open — cut mining on an example of the tectonic structure studying of an ore deposit are proved. The conclusions about the possible use of the developed technologies safe building and operation objects are drawn. The developed technologies forecasting dangerous geotechnogenic processes by means of studying massif structure of rocks and revealing modern geodynamic activity tectonic zones allow revealing beforehand the most problem sites for building, to choose optimum parameters engineering constructions that provide decrease in risk of failures and accidents in the course of their building and operation.

The article is made ready on the results of investigations performed within the framework of the RF Ministry of Education and Science grant No. 02. 740.11.0722 and the UB RAS Presidium grant No.12-E-5-2050.
