The cause of this accident is coal and gas outburst, which is a powerful natural disaster in coal mine production. Fortunately, the accident was rescued in time and there were no casualties for the time being. We know that coal mine work is a very dangerous job. Coal mines were prone to collapse accidents in the past. With the development of technology, now, the probability of such accidents will be smaller. Working underground for a long time will lead to some occupational diseases, such as dermatosis, silicosis, arthritis and so on. In fact, most workers working in underground mines have little knowledge and culture, but those who can find a job outside will not go on, because after all, they are making money with their lives. Coal and gas outburst seriously threatens the production safety of coal mines, and also poses a great threat to the lives of production personnel. However, most coal and gas outburst is a precursor before outburst. For example, coal will make a sound, some sounds like crackling when frying beans, some sounds like firecrackers, and some sounds like machine gun shooting. In this case, it will attract our attention. We will evacuate quickly, let others leave quickly and ensure everyone's life safety. Coal and gas outburst sometimes makes no sound before outburst, but there are signs, such as the structure of coal seam is in a mess, coal becomes soft, dull and dull, and the air smells. If he is an old employee, he will soon realize the danger. If robots can work in mines instead of workers, then workers will not be in danger, and robots can work day and night. As long as there is nothing wrong with its parts, its production efficiency may be much higher than that of people. I hope the country can invest more time, money and manpower in these dangerous jobs, reduce the harm of the working environment to workers, ensure the safety of workers' lives and seek more benefits for workers.
