METHOD OF REGISTRATION AND SAVING OF PARAMETERS OF EXPLOSION OF METHANE DUST AIR MIX IN MINES AND "BLACK BOX" DEVICE FOR ITS IMPLEMENTATION (VERSIONS) Russian patent published in 2014 - IPC E21F17/18 G01L23/00 

FIELD: mining.

SUBSTANCE: invention relates to the field of mining industry and can be used for registration and saving of basic parameters of explosion of methane dust air mix at propagation or damping of explosions in mines. The method comprises installation in pre-selected points (survey stakes) along all over the length of mines on the path of probable propagation of fronts of air shock wave and flame of "black box" devices which record the direction of progressing or damping of explosions and simultaneously register the magnitude of overpressure in the front of air shock wave and temperature of flame front, are protected from external mechanical impacts and save the registered information until their discovery irrespective of time of search and recovery works after an accident. The versions of the "black box" device for the method implementation are offered as well.

EFFECT: design simplification, increase of work capacity and reliability of the information of the nature of process of progressing or damping of explosions in mines.
