In mine production, gas is a common harmful gas, and its accumulation and lack of air may lead to serious safety hazards. In order to better understand the causes and treatment methods of gas deficiency, today Kcalin will conduct an in-depth analysis of this problem, in order to improve the level of mine safety management.
1： The definition and hazards of gas induced ventilation
The definition of gas ventilation deficiency: Gas ventilation deficiency refers to the situation in the mine ventilation system where the gas concentration increases but the ventilation volume is insufficient, which can easily cause serious consequences such as explosions and poisoning.
Harm: Gas is a flammable and toxic gas, and the lack of ventilation in gas not only increases the risk of mine explosions, but may also pose a threat to the safety of workers.
2： The causes of gas and air deficiency in the middle
Poor ventilation: Malfunctions, blockages, or improper design of the ventilation system can lead to poor ventilation and the accumulation of gas in the mine.
Mining operations: During the mining process, the operation of mechanical equipment, rock fragmentation, and other factors may lead to the release of gas, increasing the risk of lack of ventilation.
An increase in gas emission sources: The increase in gas emission sources in the coal seam, such as the bottom of the coal seam and the boundary between the coal and the roof, is also one of the reasons for the lack of wind.
3： The characteristics and detection methods of gas deficiency wind
Features: Gas deficiency is usually accompanied by a decrease in mine ventilation airflow, an increase in gas concentration, and an increase in mine temperature.
Detection method: Use professional equipment such as gas detectors and ventilation testers to monitor the gas concentration and ventilation situation in the mine in real time, and promptly detect the phenomenon of lack of air.
4： Methods for dealing with gas and air shortage
Strengthen ventilation management: Regularly inspect the ventilation system to ensure the normal operation of ventilation equipment, smooth ventilation tunnels, and improve the efficiency of the ventilation system.
Gas drainage technology: Introducing gas drainage technology, gas is pumped out of the mine through underground drainage devices, reducing the accumulation of gas underground.
Safe operating procedures: Develop and strictly implement safe operating procedures, standardize operating procedures, and reduce the impact of mechanical equipment operation on gas.
Using gas inhibitors: Spray gas inhibitors in the mine to slow down the release rate of gas and reduce the risk of gas deficiency.
Looking ahead to the future, with the development of technology, gas exhaust treatment technology will continue to innovate. Adopting better ventilation equipment, automated monitoring systems, etc. will help to more accurately prevent and handle gas induced ventilation.
In mining production, gas deficiency is a serious safety hazard that requires high attention from mine managers and staff. By deeply understanding the causes and treatment methods of gas ventilation, and taking scientific and effective measures, the risk of mine accidents can be greatly reduced, ensuring the safety of workers.
