FIELD: mining.SUBSTANCE: method comprises the reception of acoustic signal, its amplification, a filtration, registration and comparison. The tone of sounding of acoustic signal during its loading is compared with reference sound tones from a database, then the compliance of sounding tone with a well information is analysed, the obtained data are registered and using them the explosive supply system is controlled. The device comprises a pneumatic loader with a loading hose, a receiver designed as a microphone, a signal processing system connected to the command device. The signal processing system is fitted with series connected broadband amplifier, a sound filter, a memory and analysing device with the unit of database of reference sounding tones and the demountable information media, an actuation device, an analyser of sounding tones with a setting device and the demountable information media. The command device is fitted with an executive mechanism, a spool with electromagnetic valves and a locking device installed directly on a pneumatic loader at the compressed air inlet or at the explosive outlet from the pneumatic loader to the loading hose. The executive mechanism is connected to the locking device through the spool by means of compressed air supply hoses.EFFECT: method and the device allow to simplify a design, improve accuracy of measurement and reliability of operation.2 cl, 2 dwg |
