Domestic infrastructure is expanding from the plains in the east to the west, and in the process of developing urban traffic from above ground to underground traffic, many tunnels need to be built every year. The terrain of tunnel construction is complex, and many safety accidents often occur. The safety accidents of tunnels mainly focus on dangerous accidents such as water ingress, gas leakage, toxic gas generation, and landslides.
My country is a big coal-producing country. At present, coal accounts for about 70% of my country's primary energy consumption. For a long time to come, coal will still be a very important strategic resource and play an extremely important role in my country's economic and social development. In 2007, my country's total coal output was 2.523 billion tons, which increased to 2.716 billion tons in 2008, an increase of 7.65%. However, the total number of deaths in my country's coal mines is three times that of other coal-producing countries in the world, and the safety production situation in coal mines is still very severe. In my country's primary energy production and consumption structure, coal has always accounted for about 70% of the total, especially in the In the 1950s and 1960s, coal consumption even accounted for 80% to 90% of total energy consumption. Characteristics of my country's coal industry: 95% of coal mining is underground operations. In underground coal mining, there are five natural disasters: water, fire, gas, coal dust and roof. In the production process, mining, excavation, machinery, transportation, Improper management of processes and links will lead to accidents, seriously endangering the lives of employees. The continuous coal safety accidents endanger the life of every miner, bring heavy disasters to the families of the miners, increase the production cost of enterprises, and affect the construction of a harmonious society. The frequent occurrence of mining accidents is extremely inconsistent with the political background of building a socialist harmonious society in our country, is inconsistent with the people-oriented scientific development concept, and completely deviates from the party's governing goals. The problem is imminent, otherwise there may be a risk of piling up. Formulate perfect coal mine safety production laws and regulations, and establish a relatively complete coal mine safety management organization. The state has continuously strengthened supervision and rectification of coal mine safety production, but major accidents still occur frequently. Coal mine safety is a top priority that is related to the physical and mental health and life safety of coal mine workers, as well as to the national economy.
Lithium Battery Aging Rack Fire Warning Scheme
Before some lithium batteries leave the factory, lithium battery manufacturers will put them on the aging rack for aging test. Lithium batteries come in different shapes and sizes. During the aging process, some batteries with abnormal quality will catch fire. For the fire of a single battery, the smoke in the aging room cannot be detected at all. When a single fire battery ignites the normal battery next to it, the smoke will be detected, and the fire will be difficult to extinguish by this time.
Culvert Water Level Monitoring Scheme
Most of the culverts in the city are located in low-lying places, and the sudden heavy rain often floods the culverts with water. When the culvert is flooded, passing vehicles can easily drive into the water and cause an accident.
This system uses a combination of various sensors to accurately know how deep the water level is.
On March 11, 2018, the 13th National People's Congress passed the "Amendment to the Constitution of the People's Republic of China", which pointed out: to promote the coordinated development of material civilization, political civilization, spiritual civilization, social civilization, and ecological civilization.
The "Decision of the Central Committee of the Communist Party of China on Several Major Issues Concerning Comprehensively Deepening the Reform" adopted by the Third Plenary Session of the 18th Central Committee elevated the construction of an ecological civilization and a beautiful China into a national strategy. Marked by the "Overall Plan for the Reform of Ecological Civilization System", the reform of the basic system of environmental governance has been deepened and reformed rapidly. "A series of reform actions such as vertical management have brought great challenges to environmental protection work.
