Analysis Of Occupational Health Investment Decision-making In Coal Mines And Iron Mines

Objectives In order to improve the utilization rate of enterprise occupational health input and minimize the loss caused by occupational diseases,we discussed the connotation and category of the occupational health investment and put forward the idea of occupational health investment decision-making according to the input-output model.Methods Discussed the establishment of the occupational health input-output table of coal mines and iron mines.Introduced the concept of occupational health as one product to the link of the table establishment,and described the ideas of the occupational health inputoutput table design.Analyzed the composition of the table qualitatively,and established the form expressed in mathematical symbols by using the parameters in the tabla.Established the mathematical model of enterprise occupational health input and output using of occupational health input-output table,then got four mathematical expressions related consumption coefficients and the line model and the column model represented by matrix.Established occupational health investment decision-making model,and discussed the rationality of occupational health investment based on data envelopment analysis(DEA)model.Analyzed the production data in 2014 of a coal mine in Shanxi province and a iron mine in Hebei province in China as examples.Got data by accessing the material.Analyzed the improve extent of the five components in the occupational health investment structure and came to the the enterprise occupational health investment emphasis in the future.Results 1 Established the occupational health input-output table of the coal mine,then established the mathematical model of occupational health input-output of the mine.Established the occupational health investment decision-making model including the following three parts: the occupational health investment and the output ratio model,the occupational health input-output ratio model,the occupational health investment structure analysis model.After analyzed the coal mine,we got the occupational health input-output model to connect the coal output value and the final output value,energy consumption and occupational health total investment in the occupational health input-output table by a parameter ?.We concluded that the occupational health investment and the output ratio was 0.0127,the enterprise occupational health investment was relatively poor,and the space could be improved is more than 4 million RMB.and occupational health inputoutput ratio was 1/0.123,the occupational health input had not yet get apparent output,i.e,there was no effective occupational health benefit.The occupational health investment priorities of this coal mine in the future are workers' personal protective equipment expenses and daily occupational health management expenses,the amount should be102122 RMB and 84017 RMB respectively.2 Established the occupational health inputoutput table of the iron mine,then established the mathematical model of occupational health input-output of the mine.After analyzed the iron mine,the iron production was connect with the final output,energy consumption and total input in occupational health by?.We concluded that the occupational health investment and the output ratio was 0.0045,the occupational health investment was poor and could be improved from the current 5.11 million to 50 million.The occupational health input-output ratio was 1/0.046,the occupational health input had not yet get apparent output,i.e,there was no effective occupational health benefit.The occupational health investment priorities of this iron mine in the future are workers' personal protective equipment expenses and educational expenses for occupational health,the amount should be 819498 RMB and 489428 RMB respectively.Conclusions Through the establishment occupational health input-output table of coal mines and iron mines,the relationship between occupational health investment and corporate profits could be clearly reflect.Found out the main issues of occupational health investment and the future adjustment of the direction.Optimized the occupational health investment structure.
