How tired are the front-line workers in state-owned coal mines (annual output of 2 million tons)? How high is the risk factor?

Well, there is really no concrete quantifiable figure to explain how tiring this is and how high the risk factor is. I work in a mine, and our mine has an annual output of 2.4 million tons. Let me talk about it based on the actual situation of our mine!

First, coal mines are divided into three shifts (some coal mines have four shifts), namely the 8 o'clock shift, the 4 o'clock shift, and the 0 o'clock shift. The 8 o'clock shift means working at 8 o'clock in the morning, the 4 o'clock shift starts at 4 o'clock in the afternoon, and the 0 o'clock shift starts at 12 o'clock in the evening. Each shift will only rotate once a month. For example, if you work at 8 o'clock this month, you will have to work at 8 o'clock every day until the end of this month, and then switch to other shifts next month.

2. Theoretically, the working time is 8 hours, but in fact, no matter which shift the workers work, the working time from changing clothes and going down to the well to ascending the well and taking a shower is between 10 and 12 During the hour, sometimes the task on duty is not completed or other situations occur, and this time is even longer.

3. It’s hard to say in terms of hazards. The most dangerous factor that threatens the safety of coal mine workers now is gas, followed by water, and the third is the roof. However, in terms of gas, each coal mine now has a management system and a monitoring system, and they are treated first and then mined. Once the gas exceeds the standard, people have to be evacuated, so the danger is there but not as terrible as most people imagine.

4. The dangers of water damage and roof are far less than that of gas. Generally, mine leaders and technical personnel will be prepared for water damage warning and prevention in advance. As for the roof, today's underground mines are not supported by wood materials as before. Now they are supported by metal materials, and the support strength is still reliable.

Fifth, in general, there are dangers in coal mines, otherwise coal mine accidents would not happen every year. But on the other hand, there are many people who have worked in coal mines all their lives and never had an accident or injury. When working in a coal mine, I think the following are the main things to ensure safety: 1. Keep your ears and eyes flexible at all times, and be more vigilant when you find any abnormality. First, tell others about the abnormality you find, and then everyone can think about it together. To solve the problem, you must not deal with it alone. For example, when you find that the shed used for support is bent or broken, don't deal with it silently; 2. Never go to places that you cannot go, such as blind alleys, Abandoned alleys, etc.; 3. Follow the instructions of safety leaders or personnel. There are personnel (safety supervisors) specifically responsible for supervising safety work in the mine. They know better than others which places and conditions are safe or unsafe, and they are not allowed to do it. It's best not to do it. 4. Ask more experienced workers for advice. If you have any questions, ask more, because those workers who have been working underground all year round are very experienced in safety.

Well, due to my limited abilities, that’s all I can say!
