Analysis of occupational hazards and control measures in coal mines

2.4 Vibration occupational hazard prevention

(1) Take effective vibration reduction measures for the whole body vibration, set up isolation trenches around the equipment that may have large vibration, and line with cork, rubber and other vibration reduction materials to prevent vibration transmission. (2) To take effective vibration reduction measures for local vibration, reform coal mine operation technology and equipment, improve the working system; Scientific use of vibration reduction supplies, the implementation of labor systems, strictly limit the staff's exposure to vibration time. Underground vibration hazards mainly come from the hazards of fully mechanized mining, air drill and other machinery.

2.5 Prevention and treatment of occupational hazards in poor underground climate conditions

2.5.1 High temperature control Measures

① Increase the air volume appropriately; (2) Centralized production, control the number of mining faces, and reduce the underground hot spots as much as possible. 2.5.2 Humidity Control Measures

① Increase the air volume appropriately; (2) Centralized production, the use of fully mechanized mining technology, comprehensive excavation technology and other advanced production technology, control the transport transfer point, as far as possible to reduce the labor intensity of employees, reduce their direct exposure to occupational hazard factors.

3. Study on measures to improve occupational disease prevention in coal mines

3.1 Strengthen Inspection

(1) Quality control of on-site testing equipment. The effective application of field sampling equipment plays a crucial role in the detection results. Therefore, quality control of field sampling equipment should be strengthened. Before the field test, the equipment should be verified to ensure the stability, sensitivity, reliability, safety and standard of the equipment. In the process of equipment management, the newly purchased equipment should be inspected to ensure the accuracy of the equipment, and each equipment should be managed exclusively, equipment files should be established, and equipment should be inspected, repaired and maintained regularly. (2) Quality control of the on-site testing environment. For example, when selecting a dust detection site, it is usually selected in a place with strong occupational hazard factors and long exposure time of workers. The sample is mainly people who are exposed to high levels of harmful substances for a long time.

3.2 Implement the main responsibility of the enterprise

Enterprises should seriously implement the main responsibility of occupational health stipulated in the Law on the Prevention and Control of Occupational diseases, change the concept, and regard occupational health work as the basic obligation that enterprises should complete, rather than passively complete the task. Enterprises should improve the occupational health management institutions and management teams, improve the level of management. Strengthen occupational health training and education for managers and employees, and give equal importance to occupational health training and production safety training. At the same time, strengthen occupational health monitoring, improve the occupational health files of employees, and regularly check up on employees.

3.3 IT application in prevention and control will be promoted

More than 40 years ago, the United States began to explore the information construction of occupational disease prevention and control, and has accumulated rich experience in the organization and construction of occupational disease prevention and control electronic health records, standard formulation, fund raising, privacy and security protection. In recent years, China's Internet +, big data, cloud computing, artificial intelligence and other information technologies have developed rapidly, making full use of modern information technology, breaking departmental barriers, eliminating information islands, strengthening inter-departmental information sharing and utilization, and establishing an efficient occupational health information supervision and management platform. Establish a monitoring, reporting and management network for key occupational diseases and occupational-disease-inductive factors, carry out occupational health risk assessment, and grasp the characteristics, degree and trend of morbidity in key groups and key industries, so as to fundamentally improve the efficiency of prevention and management of occupational diseases.
