60 coal mines in Shanxi stopped production due to flood disaster 1 The recent heavy rainfall and flood disaster in Shanxi touched people's hearts, which has affected 1 1 city, 76 counties (cities, districts), 175.7 10000 people.12000.
Shanxi is a big coal province, and the continuous precipitation and geological disasters have also adversely affected the local coal industry in Shanxi.
According to the news of Shanxi Provincial Emergency Management Department, as of June 8 10, Shanxi has stopped production of 60 coal mines, 372 non-coal mines and 4 hazardous chemical enterprises10, stopped construction projects 1035 and closed scenic spots 166.
According to the latest news on June 10, due to heavy rainfall, six coal mines in Shanxi still stopped production due to abnormal underground water inrush, and they need to wait for the safety risk assessment of coal mines before resuming production.
Jinzhong, Linfen and Lvliang, which were seriously affected by the flood, are the main producing areas of coking coal, while the production of thermal coal in Datong and Shuozhou has not been significantly affected.
Shanxi coal transportation is also less affected. The data shows that from June 65438+1October 65438+1October 8, the average daily coal transportation of Shanxi Railway decreased slightly compared with the same period of last year, but it was not because of the flood disaster, but the centralized maintenance of Daqin Railway this autumn was three days earlier than last year.
In addition, listed coal enterprises such as Meijin Energy and mountain coal international said that they have started the work of risk elimination and emergency safety production ahead of schedule, and the production and operation have not been affected yet.
According to public information, by the end of 2002 1 and1,there were 670 coal mines in Shanxi province.
In 2020, Shanxi's raw coal output reached 1.63 billion tons, up 8.2% year-on-year, surpassing Inner Mongolia and becoming the largest coal-producing province in China again.
The reporter noted that since the beginning of this year, the domestic coal market has been tense and the coal price has been high. As a big coal province, Shanxi has played a "ballast stone" role in ensuring the national energy supply.
On September 29th, Shanxi signed long-term coal supply contracts with Hebei, Shandong, Jiangsu, Zhejiang, Tianjin and other provinces 14. According to the relevant requirements, local Jinneng Holding Group, Shanxi Coking Coal Group, Lu 'an Chemical Group and Huayang New Materials Science and Technology Group will undertake the supply guarantee tasks of nine provinces including Jiangsu, Jilin, Anhui, Zhejiang, Shanghai, Henan, Hainan and Shandong.
Faced with the double pressure of flood and supply guarantee, some large coal enterprises in Shanxi have taken on the heavy responsibility of increasing coal production and ensuring supply while fighting disasters and providing relief.
It is reported that in this coal supply guarantee task, Jinneng Holding Group docked the coal supply of six provinces (autonomous regions and municipalities) such as Guangxi and Jiangsu. In order to fully fulfill the task of ensuring supply, the Group continuously optimizes the workflow, and goes all out to do coal loading, port loading and unloading, user emergency treatment and other work to ensure the smooth operation of production, transportation and sales. By scientifically optimizing the production layout, reasonably organizing coal production, Lu 'an Chemical Group actively promotes the scientific and efficient organization of coal transportation, and fully completes the task of ensuring supply.
In addition, yongtai energy 10 revealed in the evening that Jintaiyuan Coal Mine and Sendayuan Coal Mine owned by the company have been incorporated into Baodi Coal Mine in Shanxi, and the output is expected to increase by 225,000 tons in the fourth quarter of this year. After completing the procedures of coal mine nuclear increase, the total production capacity of the company's main coking coal and blended coking coal mines will increase from the current 9.3 million tons/year to 6.5438+002 million tons/year. Yongtai energy said that the company will do its best to do a good job in production safety, tap the potential of increasing production, and fully increase production supply on the premise of ensuring safety.

Geometry of flood disaster in Shanxi
Shanxi Province is located at the eastern end of the Loess Plateau, and there is a regular precipitation season from June to September every year. According to the data, the average monthly precipitation in June of 65438+ 10 in Shanxi Province was only 3 1. 1 mm ... But in the process of this heavy precipitation, the daily precipitation of 59 national meteorological stations in Shanxi Province exceeded the historical extreme value of the same period since the establishment of the station, and the accumulated precipitation of 63 national meteorological stations exceeded the historical extreme value of the same period. From 20: 00 on February 2 to 8: 00 on October 7, 65438, the average precipitation in Shanxi Province reached 1 19.5mm, which was three times that of 10. According to the news of China Meteorological Bureau, the precipitation in 18 counties (cities, districts) exceeds 200mm, and that in 5 1 county (city, district) is between 100 ~ 200mm, with the maximum accumulated precipitation of 285.2mm, which is characterized by large accumulated rainfall, long duration and outstanding extreme value.
10 10 in the morning, Yan Xin, a meteorological analyst at China Weather TV, released a North China radar puzzle and wrote, "At present, the rainfall in Shanxi has come to an end, and there will be no heavy rain in Shanxi for the rest of this year." However, while the weather forecast shows that the precipitation in Shanxi Province has ended, there are still 26 early warning signals in Shanxi Province, including gale, frost and cold wave warning, and other secondary disasters caused by heavy rain are still severe. Affected by continuous heavy precipitation, the river is in local danger and the flood control pressure is high. According to the news released by Yuncheng, on the 7th, the flood peak flow of Fenhe River, the largest river in Shanxi Province, was1125m3 per second, which was the largest flood peak crossing in recent 40 years. According to CCTV reports, the flow of many rivers in Jinzhong, Shanxi Province has reached the highest value in recent decades. In addition, landslides and ground collapses occurred in parts of Jinzhong, Lvliang and Linfen. At present, Shanxi has launched a Class III emergency response to provincial geological disasters and a Class III emergency response to provincial natural disaster relief, making every effort to do a good job in flood control and disaster relief.
Causes of flood recurrence
According to the analysis of the national natural disaster consultation in the first three quarters by the emergency management department and other departments and units, the rainy season in northern China started early and with strong intensity this year, and the autumn flood situation in the third quarter was severe. The affected areas in Shanxi and other places overlap with the previous period, which aggravated the disaster losses.
However, after 10 months, extremely abnormal large-scale continuous rainfall occurred again in Shanxi Province, causing serious floods. According to CCTV reports, the heavy rainfall process in Shanxi has the characteristics of large accumulated rainfall, long duration and extremely prominent. The precipitation in the early stage of the process is accompanied by lightning and strong convective weather, and the temperature drops sharply and continues to fall in the later stage, which has a great impact and a wide range.
Where did this unusual rainstorm come from? According to the news released by Shanxi, experts analyzed three reasons: First, the atmospheric circulation situation is stable. The unusually strong western Pacific subtropical high first extended westward and then lifted northward, and then remained stably in Huanghuai area, forming a stable circulation situation in Shanxi with the low-value system of westerly belt, which is beneficial to the long-term precipitation weather in Shanxi. Second, rich water vapor conditions. The southerly airflow on the west side of the subtropical high and the low-level southwest jet continuously transport the water vapor from the South China Sea and the Bay of Bengal to the south-central part of Shanxi through the southwest region, providing a rich source of water vapor for the continuous precipitation in Shanxi. Third, the low-level conditions last for a long time. Under the stable weather situation, the low-level shear line convergence system was maintained for a long time, and the precipitation echo repeatedly passed through the central part of Shanxi. The complex topography of Luliang Mountain and Taihang Mountain in Shanxi increased the precipitation of the easterly airflow, resulting in heavy precipitation in the central part of Shanxi and northern Linfen.
What is the impact of coal mine shutdown on the supply of thermal coal under heavy rain?
According to the data of the National Bureau of Statistics, in 2020, the national raw coal output above designated size will reach 3.84 billion tons, of which Shanxi's raw coal output will be 654.38+0.63 billion, an increase of 8.2% year-on-year, exceeding a quarter of the national raw coal output, making it the first coal-producing province in China. By the end of 2002 1 and1,there were 670 coal mines in Shanxi. Before the heavy rainfall, Shanxi Province just signed a medium-and long-term coal supply contract with Hebei, Shandong, Jiangsu, Zhejiang, Tianjin and other provinces (autonomous regions and municipalities) on September 29th to ensure energy supply. The central enterprises in Shanxi will guarantee five provinces (cities) such as Tianjin, Fujian, Hebei, Guangdong and Liaoning; Jinneng Holding Group connects with six provinces (autonomous regions and municipalities) including Guangxi, Jiangsu, Jilin, Anhui, Shanghai and Zhejiang; Shanxi Coking Coal Group undertakes the task of ensuring supply in Henan Province; Huayang New Materials Science and Technology Group undertakes the task of ensuring supply in Hainan Province; Lu 'an Chemical Industry Group undertakes the task of ensuring supply in Shandong Province, and the others are undertaken by coal enterprises in various cities in Shanxi Province. It is estimated that by the end of February this year, all the medium and long-term coal contracts signed by Shanxi and 14 provinces (autonomous regions and municipalities) will be fulfilled. According to the data of Shanxi Provincial Emergency Management Department, 60 mines in the province stopped production due to heavy rainfall in June 5438- 10/-July, which caused market voices to worry that floods would affect coal supply. According to Xinhua News Agency, the rainfall has had a certain impact on the production and transportation of Shanxi coal mines, but the impact is small, because Jinzhong, Linfen, Lvliang and other cities with severe disasters are the main coking coal producing areas, and the production of thermal coal in Datong and Shuozhou has not been significantly affected. At present, there are still six coal mines in Shanxi that have stopped production due to abnormal underground water inrush, and can resume production after the safety risk assessment of coal mines does not affect safety production. 10 On June 6th, the Office of the Leading Group for Coordination and Support of Coal, Electricity, Oil and Gas Transportation in Shanxi Province issued the Notice on Incorporating Some Coal Mines into Guaranteed Coal Mines and Organizing Production as Required, which included the coal mines with an annual output of 5/kloc-0 from June to August in 2002 and the coal mines with a planned nuclear production capacity of 98 in 20021year into guaranteed coal mines.
65438 10/8, Shanxi Provincial Emergency Management Department issued a notice saying that emergency departments at all levels and coal mining enterprises should clearly understand the grim situation in the autumn rain flood season, strengthen the identification of major risks and the investigation and management of hidden dangers, strengthen various emergency measures in coal mines, and further improve coal mine safety prevention.
