Description

детектора 3, преобразовател  4, накопител  5 и индикатора 6.detector 3, converter 4, accumulator 5 and indicator 6.

При растворении солей в стакане 1 содержащийс  в них газ вырываетс  с треском . Микрофон воспринимает их, преобразует в электрические сигналы, которые поступают на усилитель 2 с регулируемой отрицательной обратной св зью, величина которой зависит от вида раствор емой соли. Соли с малым содержанием газй создают незначительные редкие одиночные разрывы, сигналы от которых после з силител  пода-, ютс  непосредственно в накопитель. Соли с большим содержанием газа, создающие групповые разрушени  кристалла, а также интенсивные одиночные разрывы, имеют значительные уровни шумовой характеристики с различной длительностью. Поэтому сигналы после усилени  детектируютс  в детекторе 3 и преобразуютс  в преобразователе 4 и затем поступают в накопитель. По величине накопленного сигнала суд т о степени выбросоопасности пород.When salts are dissolved in glass 1, the gas content in them is pulled out with a bang. The microphone senses them, converts them into electrical signals, which are fed to amplifier 2 with adjustable negative feedback, the value of which depends on the type of soluble salt. Salts with low gazy content create insignificant rare single gaps, the signals from which, after s sieve, are fed directly to the reservoir. Salts with a high content of gas, creating group destruction of the crystal, as well as intense single gaps, have significant levels of noise characteristics with different duration. Therefore, the signals after amplification are detected in detector 3 and are converted in converter 4 and then fed to a drive. The magnitude of the accumulated signal is judged on the degree of outburst risk of rocks.

Наличие детектора, преобразовател  и малоемкостного накопител  позвол ет регистрировать как резкие и одиночные разрывы кристаллов солей (мала  газоносность ), так и групповые (больша  газоносность ) разрывы кристаллов солей. Низковольтное автономное питание, взрывобезопасное исполнение прибора, незначительное врем  измерений позвол ют производить определение наличи  выбросоопасных зонThe presence of a detector, a converter, and a low-capacitance accumulator allows registering both sharp and single breaks of salt crystals (low gas content) and group (large gas content) breaks of salt crystals. Low-voltage autonomous power supply, explosion-proof device design, short measurement time allow determination of the presence of outliers.

непосредственно в рабочих забо х, что значительно повышает достоверность прогноза. Проведенные испытани  прибора на рудниках , опасных по внезапным выбросам, показали надежность его работы. Внедрение изобретени  обеспечит безопасность труда и даст условный годовой экономический эффект в 200-300 тыс. рублей.directly in the workplace, which significantly increases the accuracy of the forecast. Testing of the instrument in mines, dangerous by sudden emissions, showed the reliability of its operation. The implementation of the invention will ensure occupational safety and give a conditional annual economic effect of 200-300 thousand rubles.
