The application of input and output analysis in coal enterprises

摘要

Safety input is an important factor to influence accidents in coal enterprises.In order to quantify safety input and output,this article applies the input and output analysis to coal enterprises,setting up the input and output table based on the character of coal enterprises.Then,it shows the idea that safety is a product,and analyzes the main parameters in the table.Finally,it solves the value of safety input when the total output is definite,figuring out the ratio of safety input and output,and expounds how to obtain the greatest output with the limited investment,which provides a new view for the sustainable development of coal enterprises.
