Comprehensive Evaluation And Forecast Of Security System In Chengchao Iron Mine

Mine safety assessment is the important component of safety administration , according to Scientific procedure and method, dangerous factor and the possibility of accident is investigated and Analyzed,and then expressed with established safety grade. According to current scientific and technological level and economy condition ,We will bring forward effective safe practice to removing danger or lowering danger to a minimum,and then Pursue minimum accident rate,the fewest loss and optimum safety invest in beneficial result.As the key that modern mine safety,mine safety estimates is very important in the modernization and Scientific of safety administration.Firstly, Thesis have analysed and identified dangerous and harmful factor of Cheng Chao iron mine. We have summed up the kind ,cause and the place of existence dangerous source kindSecondly, We can think that the factor in mine safety assessment is random and the relation with the accident is fuzzy and the factor correlates and interacts. And then Adopt mark given by expert and definite degree of membership, according to safety grade class, and get weight of every index,standard and unit by the expert consults law. At last we make use of the fussy theory model to get safety class.At last, Thesis bring Repeated moves law of Time forecast theory and Correlation degree analyse and to mine safety as innovative point . We consider mine accident is not by accident and continuance on time .we statistics the fact that probability happened in the accident to the past few years, and then by time forecast law we estimated mine accident in 2008 occurrence rate. We have discussed the safety in production inputs and high school record talented person's proportion two big aspect. We extracts Pessimistic interrelatedness between the high school record talented person's proportion and the mine 1,000,000 ton mortality rate pessimistic interrelatedness. We extract Pessimistic interrelatedness between the safety in production inputs and the mine 1,000,000 ton mortality rate. then we has compared the safety in production inputs and the high school record talented person to mine accident rate influence.We can completes the mine safety work on macroscopic.
