FIELD: mining.
SUBSTANCE: method of assessment of parametre characterising current stage of charge of anti-gas filter consists in following: power source of measuring block is turned on; further, electric capacity between electrodes installed in zone of charge placement is measured by means of capacitometer; electric signal generated at output of metre and proportional to measured electric capacity is supplied to signal input of comparing device, wherein this signal is compared with test signal coming from output of test signal generator; also test signal determines threshold value of measured electric capacity Ccr, characterising critical exhaust of charge.
EFFECT: operative control over current stage of charge of anti-gas filter directly during its usage.
