Study On Current Situation And Control Of CWP In A Coal Mine

ObjectivesTo know the epidemic and control situation of coal worker's pneumoconiosis (CWP) in TangShan coal mine which is subordinated to Kailuan mining industry group in Hebei province and provide scientific basis for establishment and implementation of control measurement of coal worker's pneumoconiosis.Methods1. Collect the coal mines'basic data, development history,dust prevention information, case history folder. And then arrange,classify,summary and analysis it.2. Both quantitative and qualitative methods were applied on the study.204 coal workers, were interviewed with structured questionnaire. Focus groups discussion included 8 groups of coal workers. 12 occupational health personnel, 8 dust prevention workers, 7 dust monitor workers, 5 government officers were interviewed individually using prepared guidelines. The database was established based on the obtained quantitative material using Epidata3.0 and carry on statistics processing by the SPSS13.0 for windows statistics software package.Results1. From 1952 to 2007 there were 592 Pneumoconiosis patients, and 293 alive. The prevalence of pneumoconiosis in Tangshan coal mine is 3.82%.2. With time going , the proportion of categoryâ… pneumoconiosis was gradually increased , while categoryâ…¡andâ…¢were gradually decreased; worker's age and working years that catch Pneumoconiosis both have the increasing trend. However new Pneumoconiosis cases are with the trend of going down in a short term. Coal worker's pneumoconiosis(CWP) merged with tuberculosis are also with the decreasing trend, and the percentage of tunnelling workers goes down while the percentage of coal mining workers mounts .The trend that the time for dust elimination in the wake of the diagnosis of is also going down.3. There are some characteristics of the recognition that people have awareness on the topic of preventing pneumoconiosis: They are very aware of the dust danger and the necessity of the measure for dust prevention while they are not very familiar with the country's law for controlling dust, the right for worker's health, and the supervision for dust.4. The prevention material's using percentage for the workers who contact with dust directly is only 75.5 percent which is low, the frequency is also very low that the percentage for those who use prevention material each time is only 20.6 per cent. low consciousness of using prevention material is the main reasons for the worker's not using prevention materials.5. The percentage of occupational health surveillance is only 30.6 percent which is low. The reasons may be that the limitation of the occupational health surveillance fees, occupational health surveillance affects production, and the workers'ignorance and enterprise's indifference.6. The devices for preventing dust go well except for some cases of not running. So the supervision for the dust density may have some bugs.7. It is a big problem that there are not adequate funds for professional occupational disease agency. The funds for enterprise's dust control and supervision departments are adequate.Conclusions1. With time going, the incidence rate of pneumoconiosis was gradually decreased, but the The prevalence of pneumoconiosis situation was still severe.2. There are still some questions on the prevention and control of the pneumoconiosis, they were high in recognition of the dust danger, less knowledge on the nation policy of pneumoconiosis'prevention, the percentage of occupational health surveillance is low, the prevention material's using percentage is low too, there are not adequate funds for professional occupational disease agency.Recommendations1. Strengthen the institution,implementation and control of the policy which made by each government, and raise the recognition of control pneumoconiosis, in order to make the item enough money and finally control pneumoconiosis. Made all the control pneumoconiosis sections coordination, and all the pneumoconiosis prevention progress continuity, and the management procedure systematics, to ensure the nation policy and the government policy enforce successfully.2. Enforce the transformation of occupational disease agency, identify it's position and relegation, institute it's occupational disease prevention planning according to the occupational disease prevention law, and to provide the professional technologist,the instrumentation according to the prevention planning.3. Institute long-term stable health education and health promotion planning, promote the medical professional level or made the occupational disease prevention personnel participate the professional technical training, in order to make the occupational disease prevention knowledge spread.4. Set up and perfect the occupational health surveillance, enforce the occupational health management, to ensure the occupational health surveillance implement.5. Set up the rules and regulations of personal protective articles, and execute it successfully, raise personal prevention knowledge, apply comfortable high performance economic personal protective articles to raise the usage of it.
