Mine Gas Safety Solutions The Need for Gas Detectors

The following dangerous gases are mainly found in mines.

1. methane (CH4), contained in the coal seam will be released during the mining process, is a flammable and explosive gas.

2. Carbon monoxide (CO), the explosives blasting in the digging work will produce CO, which will cause poisoning.

3. carbon dioxide (CO2), miners' breathing and spontaneous combustion of coal seams in the mine will release CO2, high concentration can cause asphyxiation. 4. hydrogen sulfide (H2S), a flammable and explosive gas.

4. hydrogen sulphide (H2S), which is a highly toxic gas produced by some sulphur-containing minerals.

5. Oxygen (O2), oxygen will be consumed with time in the closed mine, resulting in oxygen deficiency.

6. mine fugitive gases, such as a mixture of methane, nitrogen, and carbon monoxide.

7. asbestos dust, which is produced in some mines and can damage the respiratory system.

8. Radiation gas, some uranium mines will release radiation gas such as radon after mining.

How to ensure the safety of mining operations?

1. Strengthen the construction of ventilation system to ensure sufficient supply of fresh air and exhaust gas discharge.

2. install reliable gas detection and alarm systems to monitor the concentration of dangerous gases such as methane and carbon monoxide in real time.

3. Judge whether it is necessary to wear respirator to enter the operation according to the result of gas detector.

4. strengthen the construction of mine infrastructures such as electricity, ventilation, transport, etc., and use intrinsically safe equipment and protective equipment.

5. formulate scientific and reasonable ventilation and monitoring plans to guide the mining of the mine roadway.

6. carry out high-temperature work protection and equip cooling protective equipment.

7. strengthen the construction of mine emergency rescue system, and improve the accident emergency plan and drills.

8 Strengthen the safety training and education of miners, and enhance their awareness of preventing gas hazards.

9. implement the production safety regulations, supervise the staff to strictly comply with the operating norms.

10. Regularly carry out comprehensive safety inspections of the mine, checking for potential safety hazards.

The main applications of gas detector in the mine.

1. Detect the concentration of methane in the mine, methane is the main dangerous gas in the mine, and its concentration needs to be monitored in real time.

2. Detecting carbon monoxide concentration, carbon monoxide comes from blasting and combustion in the mine, which needs to be monitored.

3. detect the oxygen concentration in the mine, low oxygen concentration will lead to hypoxia hazards.

4. checking for toxic gases such as hydrogen sulphide, which can cause respiratory problems for miners.

5. analysing the gas components of the mine, understanding the composition of the gas in the mine, judging whether it is suitable for the personnel to enter the operation, and judging whether the gas concentration exceeds the standard according to the gas detection results.

6. analyse the cause of the accident, analyse whether the accident is caused by a certain gas exceeding the standard.

7. Dynamic monitoring of gas changes in the mine, real-time monitoring of gas concentration changes in the mine.

Mine gas safety solutions - in the mine operation, usually need to use both fixed and portable gas detector.

1. fixed gas detector fixed installation in the main areas of the mine, real-time monitoring of methane, carbon monoxide and other gas concentrations, and monitoring room networking, remote monitoring.

2. portable gas detector: operators need to carry into the mine operation, can detect the local area of the gas concentration, to ensure the safety of the operating environment. At the same time, it is also convenient for maintenance personnel to carry overhaul.

In contrast: fixed gas detector can provide comprehensive, dynamic, remote gas monitoring data. But can not be flexible mobile.

Portable gas detector can be flexibly moved to any location for detection, but the data can not be transmitted remotely, and can not achieve the effect of comprehensive monitoring.

Therefore, mine safety production needs to combine the advantages of both fixed and portable gas detectors for comprehensive monitoring.
