With the continuous improvement of underground safety in coal mines, the widespread application of gas monitoring systems, and the detection methods of harmful gases are also becoming more and more perfect. Major and medium-sized mines have formed a detection system that combines manual fixed-point, regular detection and automatic monitoring. Among manual detection methods, in addition to sampling analysis, the most widespread use of portable gas detectors is the rapid measurement method.

The mine is a place where a closed space and a variety of gases meet. In order to fully ensure the safety of the environment in the pipeline, it is necessary to monitor its internal environment to achieve real-time and automatic monitoring of the mining environment under the mine. Its importance is self-evident.

By configuring the corresponding sensors and alarms, and transmitting the monitoring signal to the monitoring center through communication, the data is analyzed through the supporting integrated management software. Through the software, the geographical location, measured value or working status of each measuring point is continuously collected. If there is an abnormality, the system will automatically generate an alarm (sound and light alarm, text message alarm, etc.) to notify the relevant personnel as soon as possible, so as to eliminate the possible dangerous situation in the bud, so as to avoid causing large economic losses and affect the management. The normal work of.
