A few days ago, the water conservancy department carried out anti-ice blasting on some sections of the Heilongjiang section of the Sino-Russian border river. The length of the ice surface of this blasting reached 8400 meters, the highest in the past years. Simply put, anti-ice blasting is to make a long hole in the thick ice on the river, then put explosives in each hole, and finally blast the ice at the same time. Some people may not understand that there is thick ice on the river, so people had better travel safely on the river. Why blow up the ice? There is naturally a reason for this. Let's look at the local intentions.

Blasting is the detailed location of ice explosion in Heilongjiang to prevent ice flood disaster. Located in Huma County, Daxing 'anling, it includes Jinshan section and Jiangdao section of Heilongjiang, as well as the blasting section of Mohe Arctic Village. There is much precipitation in this area, and the temperature rises rapidly. Will it happen? Talk backwards? There is a greater possibility of ice flood disaster. So-called? Talk backwards? That is, when the temperature and light are gradually warming up, the ice in the downstream has not melted, and the ice in the upstream has melted into ice. At this time, the upstream is in a state of river opening, and a large amount of ice will accumulate in the upstream and cannot flow downstream, gradually forming an ice dam on the river surface to prevent the river from flowing downstream. A large amount of river water will be deposited here, which will cause the river to flood around and pose a threat to people's lives and property on both sides of the strait. This is the ice flood disaster.

Has it happened many times before? Talk backwards? Therefore, the purpose of anti-ice blasting in Heilongjiang is to blow up the ice surface of the downstream river first, so that the downstream river will be in the state of opening the river first, so that when the upstream river opens in a few days, the melted ice can flow down the river without blocking or forming an ice dam, and naturally there will be no ice disaster. This is called preparing for danger in times of peace, nip in the bud, and take the lead in setting an example. It is understood that it has happened more than ten times in the upper reaches of Heilongjiang in the past hundred years? Talk backwards? Phenomenon, now every spring, the water conservancy department will carry out anti-ice blasting to avoid the ice flood disaster in the upper reaches of Heilongjiang Province.

The blasting scene was spectacular. After the day was ready, the explosives buried under the ice were detonated at the same time with the order of the on-site commander. After the explosion, the ice debris soared into the sky, forming a long row of columnar ice fog tens of meters high, just like the music fountain that broke out in the city square, but more spectacular and inspiring than the music fountain. Heilongjiang is the border between China and Russia, and Russia also has the responsibility and obligation to carry out anti-ice blasting. This action is also the result of active consultations between China and Russia. Both sides have their own blasting areas, and the blasting work in Russia has been basically completed.
