METHOD OF DEFINING OF INDUSTRIAL EXPLOSIVE GASEOUS AIR POLLUTANTS Russian patent published in 2010 - IPC F42B35/00 F42D3/04 

FIELD: explosives.

SUBSTANCE: in the proposed method there defined is the quantity of air supplied to the dead-end underground working ventilated by infusion method. EC charge with diametre not less than 50 mm and length not less than 6 charge diametres is blasted in steel shell with wall thickness not less than 5 mm in test room, which is created in the underground working by means of isolating cross-piece that has a hole for ventilating air output. After explosion ventilating air is exhausted and with the aid of gas-analyser there performed is constant measurement of toxic gases concentration till the decrease of their contents up to gas-analyser threshold response and gaseous air pollutants are calculated. Note that additionally at explosion moment there measured is EC charge detonation speed for detonation process completeness control.

EFFECT: provision of defining of explosives gaseous air pollutant at the places of their use.
