Looking at accident prevention through the Tunlan Mine accident of Shanxi Coking Coal Group

Thread Content

From the Internet: At 2:23 a.m. on the 22nd, an accident occurred at the Tunalan mine of the Shanxi Coking Coal Group, which could result in severe casualties. The mine is located in Gujiao City, which is under the jurisdiction of Taiyuan City. Zhang Baoshun, Secretary of the Shanxi Provincial Party Committee, and Wang Jun, Governor of the province, are on their way to the scene. Regarding this accident, everyone can conduct an in-depth analysis from a safety perspective, focusing primarily on the causes of the accident, in order to discuss how to truly prevent such accidents and take precautions in advance. In the early hours of February 22, a severe gas explosion occurred at the Tunlan Mine of Xishan Coal and Electricity Company, which is part of Shanxi Coking Coal Group. At the time of the accident, there were 436 workers working underground. As of 16:00 on the 25th, the Tunlan Mine accident had resulted in 77 deaths and 1 person remains missing. Currently, 114 injured people are still under observation and treatment in hospitals, 5 of whom are in critical condition. *****The Prime Minister promptly issued important instructions, ordering that urgent measures be taken to rescue those trapped at all costs, while also ensuring the safety of the rescuers and preventing secondary accidents. Following the accident, Zhang Dejiang, Vice Premier of the State Council, rushed to the site of the Tunlan coal mine accident to oversee emergency rescue efforts, paid visits to the families of the victims and those injured, and announced the establishment of an investigation team by the State Council to examine the gas explosion at the Tunlan coal mine of the Shanxi Coking Coal Group. Previously, Luo Lin, Director of the State Administration of Work Safety, and Zhao Tiechui, Director of the Coal Supervision Bureau, had already rushed to the scene for an investigation. The Tunlan Coal Mine, with an annual production capacity of 5 million tons, is a key state-owned coal mine. It was the first in the world to use \"large-section support\" in coal mining, and this technology won the \"First Prize for Scientific and Technological Progress.\" At the Tunlan coal mine, all raw coal is transported in a sealed manner underground; it is not handled in the open or on the ground, and 100% of it is processed. By-products of coal processing such as coal slime and coal gangue are also transported to the Gujiao power plant for reuse. 　　What Tunlan Mine is most proud of is its record of maintaining a zero death rate per million tons since 2004; many other mines have come to learn from this experience. As a high-gas mine, Tunlan Mine has invested substantial human and material resources in safety measures, particularly in gas control. Rescued miner Song Haijun said that the miners working in the mine receive safety training every day, and safety inspections are carried out before each shift. The mine was also equipped with a complete gas monitoring system; unfortunately, before the explosion, the system showed normal readings, which has led many experts to question its safety. After the explosion, the self-rescue devices provided to each miner underground helped many of them navigate through the long underground tunnels and escape from the clutches of death. 　　Wang Jun, governor of Shanxi Province, said at the plenary meeting of the State Council’s accident investigation team on the 24th that this accident clearly shows us that high investment does not equate to absolute safety; if there are deficiencies in equipment, personnel, or management, it can lead to serious disasters! 　　Based on the preliminary information, this accident was a gas explosion that occurred in the 12403 working area of the South Fourth mining district of this mine. The accident revealed four issues in that mining district: inadequate ventilation management, incomplete control of gas, lax on-site management, and failure to implement safety measures. “Tunlan Mine of Shanxi Coking Coal Group, a key state-owned coal mine with relatively good basic conditions for safe production, experienced a particularly serious gas accident that should not have occurred. This accident resulted in a high death toll and heavy losses, serving as a very profound lesson. ”Zhao Tiechui said that regarding the cause of this accident, the accident investigation team will need to conduct further analysis and determination after going down into the site for an inspection. 　　“The accident caused severe losses to the lives and property of the people. The Shanxi Provincial Party Committee and Provincial Government offered a sincere apology to the State Council, as well as to the State Administration of Work Safety; we are sorry for the miners who lost their lives… and we are also sorry for their families. ”At the plenary meeting of the State Council investigation team, Governor Wang Jun choked up several times while apologizing to the families of the miners who died at the Tunlan coal mine; he could not hold back his tears when speaking about the miners who lost their lives or were injured. 　　To Wang’s distress, just two days before the mine accident, Shanxi Province had held a provincial conference on work safety, attended by the secretaries and mayors of the 11 cities in the province, the secretaries and county heads of the 118 counties, as well as all the directors of provincial departments. Faced with the unexpected mine disasters, Wang Jun repeatedly condemned the attitude of \"preferring to hear criticism rather than cries\" and said, \"We can no longer tolerate cries.\" Unexpectedly, the next day, a gas explosion was heard from the Tunlan mine. 　　Zhao Tiechui said that the Shanxi Provincial Party Committee and the provincial government have attached great importance to coal mine safety production over the years, and the safety production situation in the province has been improving year by year, with the death rate per million tons being lower than the national average. However, the gas explosion at the Tunlan coal mine this time reveals serious gaps in safety production at large state-owned mines. “Although the management and production standards of large mines have **improved in recent years, this does not guarantee 100% safety; especially in large mines with long production cycles, complacency can easily arise. ” Zhao Tiechui pointed out that in order to thoroughly learn from the lessons of this accident, it is necessary to conduct in-depth investigations into four aspects: the mine’s ventilation management, the implementation of gas control measures, on-site mine management, and the formulation and enforcement of safety measures, based on the problems revealed by this accident. Luo Lin said that the investigation team will swiftly determine the causes and responsibilities for the accident, carefully draw lessons from it, and at the same time hold the relevant responsible parties accountable in accordance with the law. Luo Lin said that this particularly severe gas explosion occurred in a large state-owned coal mine, resulting in heavy casualties, and it once again reveals that there are still significant gaps and problems in coal mine safety production at the current stage. All regions, departments, and organizations must thoroughly learn from the lessons of this accident, apply these lessons to similar situations, and strictly enforce the responsibilities of enterprises as the main entities responsible for ensuring safety in production. They must conduct thorough and meticulous inspections to identify and address various safety hazards. Authorities at all levels as well as regulatory bodies must also fulfill their responsibilities in overseeing safety in production, strengthen supervision and monitoring of key industries such as coal mines and of major safety hazards, effectively prevent and curb the occurrence of serious accidents, and do everything possible to reduce the number of accidents and casualties, thereby achieving a steady improvement in the overall safety situation across the country.
