Problems solved by technology

Therefore. In order to ensure the safety of underground workers and ensure the normal production of mines, coal mine safety work must be placed in the first place in each work. The underground gas concentration directly affects the safety of the miners in the operation. In the prior art, the underground gas concentration The detection method is cumbersome, and the underground gas concentration in the mine cannot be obtained in real time

Embodiment Construction

[0015] Attached below Figure 1 to 3 The present invention will be further explained.

[0016] The downhole air monitoring method according to the present invention includes: S10: Obtaining a downhole gas concentration signal; S20: Comparing the amplitude of the obtained downhole gas concentration signal with a threshold set inside, if the downhole gas concentration signal is If the amplitude is greater than or equal to the threshold, an alarm will be generated; if the amplitude of the downhole gas concentration signal is less than the threshold, continue monitoring; specifically, the above steps include: a detection module 10, which is used to obtain the downhole gas concentration in the mine Signal; control module 20, the control module 20 is connected to the detection module, and compares the amplitude of the downhole gas concentration signal obtained by the detection module 10 with its internally set threshold, if the downhole gas concentration signal is The amplitude is gre...

Abstract

The invention discloses an underground air monitoring method, comprising the following steps of: S10: acquiring a gas concentration signal under the mine; S20: comparing the amplitude of the acquiredunderground gas concentration signal with a threshold value set internally. If the amplitude of the underground gas concentration signal is greater than or equal to the threshold, an alarm will be generated; if the magnitude of the underground gas concentration signal is less than the threshold, monitoring will be continued. The underground air monitoring method can effectively detect the underground gas concentration in the mine, and the detection data is accurate and the reliability is high.

Description

Technical field [0001] The invention relates to the field of detection equipment, in particular to a method for monitoring downhole air. Background technique [0002] Most of the coal mine production is underground operation, the geology and mining conditions are complex and changeable, there are many unsafe factors, and they are often threatened by actual hazards such as gas, coal dust, fire water and roof. Therefore, in order to ensure the safety of underground operators and ensure the normal production of mines, coal mine safety must be put in the first place of all work. The concentration of underground gas directly affects the safety of the operating miners. In the prior art, the concentration of underground gas The detection method is cumbersome, and the gas concentration in the underground mine cannot be obtained in real time. Summary of the invention [0003] The present invention aims to solve one of the above-mentioned problems in the prior art, and provides a downhole ...
