There was a gas explosion in the coal mine. How to avoid this kind of incident?

Coal mine gas explosion has always been a big problem that puzzles the coal mine industry. The direct cause of coal mine gas explosion is that gas concentration, oxygen concentration and temperature reach the critical point. Under normal circumstances, the oxygen concentration in the air has exceeded the critical value, so we can only start from the other two aspects for the time being. Specific measures are nothing more than strengthening management and improving technology and equipment.

It is reported that at 2 am on the 20th, a gas explosion occurred in a coal mine of Lu Shanxi An Group, killing four people and injuring 1 person. The rescue operation has ended and the cause of the accident is under investigation. According to media reports, the annual output of this coal mine is 6.5438+0.2 million tons, which is a coal and gas outburst mine.

Facing the whole coal mining industry, the state should strengthen qualification examination and approval and production supervision, shut down or rectify small coal mines, and promote the integration and upgrading of scattered coal mines by large groups. Promote the modern management of coal mines, strengthen safety publicity and measures, carry out mutual supervision among employees, implement safety measures, standardize mine operation management, timely check power equipment lines and mine support, and identify potential safety hazards.

After being integrated into a large company, risk responsibility management should be implemented. Before mining, we should find out the geological conditions of coal seams, avoid gas coal seams, and punish those responsible for ordering mining knowing that there are risks. Relevant departments should conduct surprise inspections of coal mines from time to time to eliminate irregular behaviors in coal mines. Minimize the risk of gas explosion from management.

When technology and equipment support and upgrade underground operations, gas detection devices should be equipped to keep an eye on gas concentration at any time, report any abnormality in time, and evacuate at the first time. If the gas concentration is about to reach the standard before evacuation, all power facilities should be shut down immediately to avoid detonating gas. In addition, the use and maintenance of ventilation equipment should be done well in underground coal mines to avoid gas accumulation in narrow spaces and keep the gas concentration below the critical point.

Finally, promote the popularization of unmanned coal mining technology as soon as possible, which is why the coal mining industry should be integrated. After the conditions are met, enterprises can promote industrial upgrading and change the situation that manual coal mining faces major security risks. Of course, the local government should also cooperate to promote the development of other industries and solve the labor problem.
