Current status and development trend of mine gas concentration detection in China

The detection of mine gas concentration is of great significance for coal mine safety production and disaster prevention and control. The method of gas concentration detection in mine is described in detail, and the method of gas concentration detection is discussed and analyzed in detail. The problems existing in the detection of the gas concentration in the mine are pointed out. In view of the existing problems, the performance of the gas detection element, the sensitivity of the detection method, the accuracy of the test result and the response speed of the test are put forward, and the size and the cost of the test instrument are further reduced. With the input of the intelligent mining, the underground gas concentration detection of the coal mine should be matched with the intelligent mining machine to form a new detection monitoring system, which has the functions of automatic calibration and real-time monitoring, realizes the rapid pre-judgment technology based on the above functions, and achieves the safe production; and the bionic sensing technology The new intelligent bionic gas sensor is developed based on the computer technology and the intelligent technology.
