MONITORING RADON EMANATIONS FIELD IN THE ZONE OF TECHNOGENOUS IMPACT

Abstract

The results of regime surveys over the radon field on
the undermined rock mass over Southern deposit of
Peschansky gpoup iron ore fields captured by displacement process are presented. Geodynamic activity forms the field of radon emanations. When
processing the radon researches results for not tectonic factors elimination on radon field formation
the method of rationing radon volume activity values in ground air is used. The received changes of
radon volume activity are confirmed by geodetic
measurements. Observations have shown sharp differentiation of the emanating field in a displacement
zone. The emanating field is characterized by high
contrast and reflects rock mass geodynamic structure. Considerable transformation of stressed-deformed field during surveys is revealed. The emanating field studying in time allows to track evolution of rocks displacement in the zone of technogenous impact of miningoperations.
