Natural and anthropogenic disasters include emergencies that occur on man-made objects under the influence
of natural processes and phenomena. For mining enterprises that count to man-made objects, dangerous natural processes and phenomena are most often deformation
processes in the rock mass and on the earth's surface,
causing the destruction of underground mine workings
and industrial infrastructure on the earth's surface.
In the practice of disaster investigation, as a rule, first of
all consider some obvious violations of technological
regulations, which in one way or another accompany the
emergency situation, leaving without attention the deeper
causes of natural origin.
Modern geodynamic movements are one of the most
common sources of accidents and catastrophes at subsurface use facilities. Naturally, they occur to some extent in all cases, and this gives reason to ignore the actual hidden, deep causes of a natural nature, such as the
structural configuration and geodynamic activity of tectonic disturbances.
Diagnostics of geodynamic activity of developed and
operated subsurface objects allow assessing the danger
of modern geodynamic movements and taking timely
measures to reduce the risk and severity of the consequences of disasters.
In order to reduce the risk of natural and man-made
disasters, there is a need to update the regulatory documents norming engineering and geological surveys for
construction design in terms of taking into account modern geodynamic activity and its impact on the formation
of the stress-strain state of the rock mass.
