1. In gold mines, e to the crushing of ore, the st concentration in the working environment is high, many workers do not know occupational protection, and pneumoconiosis has the characteristics of long onset cycle, not obvious in the initial stage, very painful and incurable in the later stage
in addition to people's misconception that st masks have good protection effect and high respiratory resistance, there are few high-grade masks, and low-grade masks are flying all over the world. Therefore, many employees choose st masks because of unprotected or wrong choice, leading to pneumoconiosis. And the gold mine has the characteristics of multiple and mass pneumoconiosis
through the following common sense, we can scientifically choose protective masks to prevent pneumoconiosis
as special labor protection articles, st masks must be certified by gb2626-2006
1. Therefore, the choice of masks should also be made according to the national standard. National standard: anti st (st, smoke, fog, microorganism). For st prevention, there are three levels of protection: kn100, kn95 and Kn90. 97%, > 95% and > 90% respectively
2. Face masks are divided into disposable, replaceable filter cotton half face mask and full face mask. For long-term occupational protection use, especially in the environment with high st concentration, heavy smoke and other ultra-fine particles, it is recommended to use the replaceable cotton filter type half mask, most disposable masks are regardless of size, and relatively few high-grade masks
3. The mask materials include silica gel, plastic, etc. the silica gel material is relatively soft and comfortable, and the facial pressure is low
4. It is particularly important to divide the size of the mask according to the national standard. Many masks are not semicolon type, the effect will vary from person to person
5. There are two kinds of masks covering the mouth and nose and covering the mouth, nose and mandible. The second kind of mask has large contact surface, good fit and low pressure feeling
6. The expiratory resistance of face mask should not be higher than 250 PA. The inspiratory resistance should not be higher than 350 PA. At present, the mouth with high technology content can achieve about 50 PA of expiratory resistance and about 100 Pa of inspiratory resistance, effectively changing the disadvantages of good protective effect and large respiratory resistance in the past
do not neglect respiratory protection. Using fake and shoddy masks, gauze, towels, etc. can easily lead to lung disease. At present, some common N100 st masks can not only ensure the protection effect, but also breathe smoothly, about one yuan a day, which can be affordable by enterprises or indivials at their own expense. At present, many domestic harsh environment in the selection of 3m8233, baoshunan 3201 and other N100 st masks.

5. Wear a collection + 2, exciting transport equipment. It's better to have an automatic mark to see monsters. It's better to hand in cat tickets
6. Huilongshi, most of the ore spots in the upper level will come out, and the lower level can go to the village and the assembly volcano for mining. The probability is not particularly high. I think the blue mineral is easier to come out. Change to cat hunting or wear a light leather suit to dig
