First of all, dust hazards
Dust is one of the main occupational hazards in coal mine working environment. Long-term inhalation of coal dust and rock dust may lead to occupational diseases such as pneumoconiosis. Pneumoconiosis is a serious lung disease, which can lead to pulmonary fibrosis, affect respiratory function and even endanger life.
Second, the noise hazard
In coal mine operation, the noise generated by the operation of mechanical equipment is also a harmful factor that cannot be ignored. Long-term exposure to noise environment may lead to hearing loss, tinnitus and other hearing damage problems. In addition, noise may also affect the mental health of workers, leading to mood swings, inattention and other problems.
Third, the harm of harmful gases
There may be harmful gases such as carbon monoxide and hydrogen sulfide in the coal mine working environment. These gases are not only strongly irritating, but also may cause damage to workers' respiratory system and nervous system. Inhaling harmful gases for a long time may lead to poisoning symptoms and even life-threatening.
Fourth, the harm of high temperature and high humidity.
The working environment of coal mines is usually relatively closed, and there are problems of high temperature and high humidity. Working in such an environment for a long time may lead to health problems such as heatstroke and dehydration. At the same time, the high temperature and high humidity environment may also affect the work efficiency and safety of workers.
Five, the harm of bad posture
In coal mine operations, workers often need to maintain a certain posture for a long time. These bad postures may lead to occupational diseases such as muscle fatigue and joint pain. In addition, maintaining the same posture for a long time may also affect the blood circulation and respiratory function of workers.
To sum up:
Occupational hazards in coal mines include dust, noise, harmful gases, high temperature and humidity, and bad working posture. These factors may have a serious impact on the health of coal miners, leading to the occurrence of various occupational diseases. Therefore, coal mining enterprises should strengthen the monitoring and control of occupational hazards and take effective protective measures to ensure the health and work safety of workers.
Legal basis:
Law of People's Republic of China (PRC) on the Prevention and Control of Occupational Diseases
Article 13 stipulates:
The employing unit shall establish and improve the responsibility system for occupational disease prevention and control, strengthen the management of occupational disease prevention and control, improve the level of occupational disease prevention and control, and take responsibility for the occupational disease hazards generated by the unit.
Article 17 stipulates:
The employing unit must adopt effective occupational disease protection facilities and provide workers with occupational disease protection articles for personal use. Occupational disease protection articles provided by the employer for individual workers must meet the requirements of occupational disease prevention and control; Do not meet the requirements, shall not be used.
Article 2 1 stipulates that:
The employing unit shall give priority to the adoption of new technologies, new processes, new equipment and new materials that are beneficial to the prevention and treatment of occupational diseases and the protection of workers' health, and gradually replace those that are seriously harmful to occupational diseases.
