Description

Gas telemetering equipment for mine

Technical Field

The utility model relates to the technical field of gas monitoring, in particular to a gas telemetry device for a mine.

Background

Accidents such as underground gas explosion and fire disaster can generate a large amount of toxic and harmful gases such as CO, CO2, CH4 and the like, and consume a large amount of O2. When the concentration of toxic and harmful gas in the scene is ultrahigh and the content of O2 is low, the life of searching and rescuing personnel is endangered, so that when rescue is carried out after underground disaster, the danger of the mine environment air within a certain distance which is not reached is detected.

Carbon monoxide (CO) is a toxic flammable and explosive gas that presents a significant hazard to industrial safety. In coal mines, carbon monoxide is one of the main gases that causes gas explosions. Both the reason of gas explosion and the products after gas explosion are related to carbon monoxide, a large amount of smoke is generated in early stage of fire disaster before natural ignition, and the main component of the smoke is high-concentration CO, so that the early stage prediction and forecast of the fire disaster can be effectively carried out by monitoring CO gas. After the carbon monoxide is sucked into the lung of a human body with the air unconsciously, the affinity of the carbon monoxide with hemoglobin is about 250-300 times higher than that of oxygen, so that the carbon monoxide is not easy to separate, the brain and the whole body tissues of the human body are subjected to hypoxia and choking to poison, when the CO in the air reaches a certain concentration value, the life safety of the human body is directly threatened, and particularly under the underground coal bed gas leakage and special coal bed geological conditions, the CO gas in a mine can be gushed out to be accumulated locally and exceed the standard. The main sources of carbon monoxide CO in mines are: blasting; mine fires; gas and coal dust explosion, etc. It is counted that about 70 to 75% of dead people are caused by carbon monoxide poisoning in gas explosion, dust explosion and fire accidents occurring in coal mines.

The "national mine safety supervision department comprehensive department regarding the notification mine safety comprehensive [ 2021 ] 12 of the alarm handling supervision and inspection work of strengthening the gas overrun of the coal mine" clearly requires: the risk monitoring and early warning system discovers that the phenomena of over-limit time of less than 3 percent of methane concentration but over-limit time exceeds 5 minutes, methane concentration exceeds 3 percent, carbon monoxide concentration exceeds 24ppm and time exceeds 30 minutes, abnormal fluctuation of methane or carbon monoxide concentration or long-time data return to zero and the like exist, and a person needs to immediately send out the device to check on site to find out reasons in time and conduct treatment according to law.
