FIELD: mining.
SUBSTANCE: invention relates to mining industry, namely, to provision of safety during works under shaft conditions, and may be used to determine paths of filtration of mine air. The method to determine paths of filtration of mine air in shafts, including introduction of a tracer into shaft atmosphere, determination of air bleeding points, samples in bleeding points and their gas analysis for availability of the tracer with the help of indicator tubes with the possibility of subsequent inspection by a chromatographic or spectrophotometric method in the stationary laboratory. A feature of the proposed method is the fact that the tracer is furfurol sprayed dispersedly into air flow in the amount from 25 to 30 mg/m3.
EFFECT: higher validity of analysis of mine air samples, expanded assortment of applied tracers and provision of their safe use for a human being.
