The Donbass region is charactenzed by enough complex mining-geomechanic conditions of an underground coal mining, beds of which are subjected to tectonical, plicative dislocations with a break in continuity, complicating a picture of stresses clistribution around working. Besides, the long coal nuning during many decades on horizons from 300-400 m to 1 1cm and more causes the problem of old abandoned underground working revealing, under which cauldrons dangerous for engineering constructions, are formed.The task of revealing of subsidence-dangerous sections of rock masses above modem horizons, being developed, that cause destabilization of the earth surface,especially in zones of local microaniplitude dislocalions with a break in continuity is also a matter of current interest.The probleni of a stressed state evaluation of rock pillars, left in mines, that are assigned to preservation of a rock mass stability above important national economic projects, is also of a great practical interest.Original resuits of geophysical express investigations, stated below, are dedicated to decision of vanous aspects of above-mentioned problems on the basis of the study, from the earth surface and under underground conditions, of objective regularities of rocks pulse electromagnetic emission manifestation, arising in them under the action of stress fields, formed in workings and above them.
