ABSTRACT
/Full article available only in Bulgarian language/

This article considers the application of selected mineral and chemical means, together
with the preparation and supply technical equipment in mines in case of different natural hazards
(massif instability, fire, methane or climate specific characteristics). It reviews the options for
use of new mineral and chemical means for insulation of the heading walls, for gaps infill for
strengthening purposes, for insulation of layer section in the corridors, for consolidation of rock
cracks, for isolation of inoperative sites, in case of construction of bridges and their ventilation
etc. New aspects of personal safety are considered in the view of the need for safe application of
the new mineral means and the respective procedures. The connective systems for strengthening
and sealing of rock cracks have been classified.
