Why does the coal mine have to prevent dust, is the coal mine dust prevention team good, and is the

Jiangsu Zhongming Environmental Protection Technology Co., Ltd. is an environmental engineering company engaged in industrial waste gas on-site research, technology research and development, process customization, equipment manufacturing, project site construction and installation, operation and maintenance. At present, the company has 8 branches in the country, including four standard production plants, which are located in Suzhou, Langfang, Hebei and Shenyang, with a total production area of more than 42,000 square meters. The company has more than 10 years of experience in environmental protection equipment manufacturing, and now has a scientific quality management system and passed the ISO9001-2008-14001-18040 quality management system and the EU CE certification.

The core products are "catalytic combustion equipment", "photo-oxygen catalytic equipment", RTO, RCO, condensation** and "low-temperature plasma equipment", and the successful implementation of waste gas treatment projects in hundreds of factories has left a good reputation in the field of VOCs waste gas treatment.

Coal mines must prevent dust, mine dust, inhaled into the lungs by underground workers, causing alveolar blockage, the lungs lose their binding to oxygen, and then cause pulmonary siliconosis, which is also an occupational disease of coal miners.

1. Mine dust, mainly rock dust, is mainly composed of silica, which is inhaled into the lungs by underground workers and combines with the alveoli, causing alveolar blockage, forming hard things, and the lungs lose their binding to oxygen, which in turn causes lung cancer. There is no cure for his disease, but only to prolong his life.

2. Shorten the life of the machine.

There are two main ones.

Clause. 1. Reduce the hazards of occupational diseases;

Clause. Second, coal dust accidents can be eliminated for coal mines with coal dust hazards.

The composition of coal is carbon. Carbon is flammable, and the toner in the air reaches a certain concentration when it encounters Mars**!

Too much coal dust accumulates in the lungs and will make it difficult to breathe, and it is not allowed!

Coal mines belong to a high dust environment, and coal dust is also relatively delicate, be sure to wear qualified dust masks, it is recommended to use the national standard first banquet KN100 dust mask for protection.

Dust masks belong to special labor protection equipment in China, and the national standard GB2626-2019 "Self-priming Filtering Anti-particulate Respirator" must be implemented, which divides dust masks into three levels: KN100, KN95 and KN90. For example, Baoshunan's 3216 KN100 and 3219 KN100 dust masks can achieve more protection efficiency against ultra-fine dust above microns.

So how to scientifically choose the dust mask that suits you?

1) Choose a compound half-mask type: disposable masks are resistant to high air leakage rate, and are not suitable for long-term or occupational protection;

2) Choose KN100 level: high dust environment and low protection rate will lead to physical injury;

3) Choose a silicone mask, which has a relatively long service life, is soft and comfortable. Wear it for a long time, it is not easy to cause allergic reactions; Masks with high hardness are easy to cause facial indentation;

4) It is extremely important that masks come in large and small sizes. It is not recommended to buy those so-called universal models of masks, different people are tall, short, fat and thin, and have different face shapes.

5) Choose a mask with good breathability: Especially the dust mask with double filter cotton + double filter surface design, which has a longer service life and is relatively smoother to breathe.

Not good, big. The coal dust is indeed very large, but the coal mining face is basically dust-proof, and it is necessary to wear a mask when working in the underground line. Therefore, the coal mine dust prevention team is not good, because the dust is very large, and occupational diseases tend to increase.

Coal mine dust prevention refers to the technology of reducing the concentration of dust in coal mines and preventing coal dust from being used by Chonghui.

Answer: The common masking dust in coal mines mainly includes coal dust, gangue dust, smoke and dust generated by coal and rock, and wind dust generated during mine ventilation.

Explanation: A large amount of dust will be produced in the production process of coal mines, of which coal dust is one of the most important dusts, mainly generated in the process of coal mining, crushing, transportation and storage. In addition, gangue dust is mainly produced during the crushing, transportation and treatment of coal and gangue mixtures; The soot produced by coal blind dust rock is mainly due to the debris and particulate matter produced by coal and rock in the process; The wind and dust generated during the ventilation process of the mine are caused by the air flow and formation damage caused by underground operations.

These dusts have a great impact on the health and production safety of coal miners.

Expansion: In order to reduce the impact of dust on coal miners, coal mining enterprises need to take a series of measures, including strengthening ventilation, wet dust reduction, closed operations, and using dust-proof equipment. At the same time, a series of policies and regulations have also been introduced to regulate and supervise the dust control of coal mining enterprises to ensure the production safety and health of coal miners.

2.Gangue dust: Gangue dust generated during coal mining and high-level operations in the mining chain.

3.Rock dust: Rock dust generated during underground mining and tunnel construction.

4.Mineral dust: includes dust generated in the mining and processing of metallic minerals such as gold, silver, copper, zinc, and iron.

5.Chemical dust shed: dust produced by the volatilization of chemicals used in the production process of coal mines, such as lubricating oil and fuel.

6.Shedding of human body**, hair, fluff, etc., as well as dust, smoke and other impurities.

Dust removal ash from coal mines often contains iron dust. Dust removal ash is a kind of solid waste in coal mine emissions, which includes ash and some other impurities in coal. In coal mines, dust removal ash is usually collected and disposed of by dust removal equipment to prevent it from polluting the environment.

Dust removal equipment usually separates solid particles and gases by physical or chemical methods, and some of these solid particles are dust removal ash containing iron powder. Therefore, the grinding dust removal ash on the coal mine may contain different proportions of iron powder, and the specific content depends on the process flow of the coal mine and the performance of the dust removal equipment.
