Изобретение относитс к области горной промышленности и может использоватьс в шахтах, опасных по газу и пыли, дл обеспечени безопасного ведени работ.The invention relates to the field of mining and can be used in gas and dust hazardous mines to ensure safe operations.
Известен способ обнаружени начальной стадии развити взрыва метано-воздушной смеси путем регистрации излучени в инфракрасной области спектра и последующего преобразовани его в электрический спгпал . Однако такой способ ненадежен вследствие ложного срабатывани датчиков от источников освещени .There is a known method for detecting the initial stage of an explosion of a methane-air mixture by detecting radiation in the infrared region of the spectrum and then transforming it into electrical radiation. However, this method is unreliable due to the false triggering of sensors from light sources.
Дл повышени надежности обнаружени взрыва в начальной стадии его возникновени и устранени помех от источников освещени по предлагаемому способу инфракрасное излучение регистрируют в средней области спектра в диапазоне длин волн от 4 до 5 мкм.In order to increase the reliability of explosion detection in the initial stage of its occurrence and eliminate interference from sources of illumination using the proposed method, infrared radiation is recorded in the middle part of the spectrum in the wavelength range from 4 to 5 microns.
На чертеже изображены спектральные характеристики излучени взрыва - 1, источников освещени , примен емых в шахтах, - 2, фильтра - 3 и приемника лучистой энергии в инфракрасной области спектра - 4. По предлагаемому способу регистратор взрыва устанавливают на рассто нии 3 - 6м от предполагаемого места возникновени взрыва. В частном случае дл защиты проходческого или добычного комбайнов - непосредственно на комбайне. Поток лучистой энергии взрыва через фильтр с полосой пропускани от 4 до 5 мкм, выдел ющий наиболее интенсивную инфракрасную полосу с максимумом на 4,4 мкм, попадает на приемник лучистой энергии, например серии СФ 4. Электрический сигнал с приемника лучистой энергии после обработки в электронной части системы обнаружени управл ет работой устройства подавлени взрыва.The drawing shows the spectral characteristics of the explosion radiation - 1, the sources of light used in the mines - 2, the filter - 3 and the receiver of radiant energy in the infrared region of the spectrum - 4. According to the proposed method, the explosion recorder is set at a distance of 3-6 meters from the intended location the occurrence of an explosion. In the particular case for the protection of a tunnel or mining combine - directly on the combine. The flow of radiant blast energy through a filter with a passband of 4 to 5 microns, which separates the most intense infrared band with a maximum of 4.4 microns, reaches the receiver of radiant energy, for example the SF 4 series. The electrical signal from the receiver of radiant energy after processing in the electronic Parts of the detection system control the operation of the explosion suppression device.
В св зи с тем, что спектральные характеристики данного регистратора взрыва и источников освещени не совпадают, система обнаружени защищена от ложных срабатываний .Due to the fact that the spectral characteristics of this recorder of the explosion and the sources of illumination do not coincide, the detection system is protected from false alarms.
