Sichuan's first level I flood control in history: Bitcoin mines in Leshan and Ya'an were affected by the disaster and warned of geological disasters

At 5 a.m. on the 18th, Sichuan Province launched a Level I flood emergency response - this is the first time Sichuan has launched this level of response on record, which is enough to show that the current flood control situation in Sichuan is extremely severe.

The government has adjusted the once-in-50-year event rate to once-in-100-year event rate. Mines that were severely affected were in the upstream and downstream areas of the Qingyi River in Ya'an, Hongya, and Leshan, especially those directly supplied with electricity. It is estimated that 5-8 mines have been affected. However, compared with the mudslide disaster in Aba last year, it is still relatively minor.

Subsequently, the lower reaches of the Dadu River and the Minjiang River will also experience floods that exceed warning levels and protection levels. The impact on the mines will spread to other areas. Some mine owners are worried that their machines will be damaged, so they have stopped mine operations, moved out the machines and evacuated personnel.

The good news is that according to the latest Central Meteorological Observatory report, starting from the 18th, the heavy rainfall in the Sichuan Basin will begin to converge and weaken, and will temporarily come to an end until August 22nd. However, due to the saturation of soil water content, geological disasters may occur in the future, so don't take it lightly.

Since Sichuan established its flood emergency response system in 2005, it has never initiated a Level I flood emergency response, and Level II has only been initiated five times, in 2010, 2011, 2012, 2018 and August 17, 2020.

According to the Sichuan Provincial Flood Control and Drought Relief Headquarters, a once-in-a-century flood has occurred in the Ya'an urban section of the Qingyi River. Since August 15, a new round of heavy rainfall has occurred in the western and northwestern parts of the Sichuan Basin. Heavy rains have occurred in Chengdu, Deyang, Mianyang, Ya'an, Leshan, Aba, Liangshan and other cities (prefectures), resulting in urban waterlogging, fallen trees, landslides, road collapses and other situations in many places. Many highways in Sichuan Province have been blocked.

The impact in Leshan was particularly severe, with news of mines being destroyed going viral on the Internet. Traditional manufacturing was also greatly affected. For example, Leshan Shenghe Rare Earth Co., Ltd., which is engaged in the rare earth industry, suffered a total loss of more than 390 million yuan, including losses of fixed assets such as machinery and equipment, factory buildings, and inventory losses.

On the 17th, the real-time computing power of major mining farms dropped by 10%-20% because floods and mudslides in Aba, Jiulong and other places cut off telecommunication optical cables, resulting in network outages. However, the recovery speed was very fast, and the computing power of major mining pools has now returned to normal.

August is the rainy season in Sichuan. According to past experience, geological disasters and power stations' flood peak avoidance will affect power generation, so the power generation of power stations in August is generally less than that in September or even July.

The State Grid Sichuan Electric Power Company said that floods and mudslides caused by heavy rains caused varying degrees of damage to power grids in many places, and some power facilities were shut down. Active power outages and power restrictions were implemented in some severely affected areas to ensure the safety of people, equipment and lines.

However, the hydropower consumption mine built in the park this year has better flood control effects and the probability of geological disasters is relatively small.

Although the current level of flood control has been adjusted to Level I, the miners have been more prepared for the rainy season in August. Senior miners still remind that some "migrant" miners who have moved from the north are not familiar with the local conditions and need to be fully prepared.

In fact, what miners fear most is not floods, but geological disasters caused by floods. For example, the mudslide in Aba in 2019 caused 4 deaths and 19 people missing, including a power station in Yingxiu Town and a power station in Caopo Township, which had a great impact on the mine.

A similar disaster occurred again in June this year. On June 17, a mudslide occurred in Meilonggou, Banshanmen Town, Danba County, Ganzi Prefecture, destroying several local mines and leaving many people missing. According to Cover News, one power plant employee was missing, the Meilong Power Station (2,000KW installed) was destroyed, and the Annianggou Power Station (3,200KW installed) was threatened.

The meteorological department reminds that although the rainfall in the Sichuan Basin has weakened, the cumulative rainfall in the Sichuan Basin in the past 10 days has been 2 to 4 times higher than the annual average, and the rainfall in the western part has even been more than 4 times higher. The soil is saturated with water, and there is a certain lag in the occurrence of geological disasters, so we should not relax our vigilance. Affected by the rainfall, the meteorological risk of mountain torrents and geological disasters in central and northern Sichuan, western and southeastern Yunnan, southern Gansu and other places is still high, and relevant monitoring and prevention should be continued.

At the same time, Yunnan Province's flood emergency response was upgraded from Level IV to Level III from August 18. On August 18, there were heavy to torrential rains in the southern Nujiang River, Lijiang, Dali, Baoshan, Dehong, and Lincang, and heavy rainstorms in some areas. On August 17 and 18, there were torrential rains and heavy rainstorms in some areas in Yingjiang, and a flood that occurred once in 20 years occurred in the Binglang River Basin. There are many small and medium-sized direct-power supply mines in Yunnan, which will also face flood disasters.
