Quantitative Study Of The Old Factory Tin Safety Assessment

The mine safety appraisement just started in our country for several years, the massive foundational works have not been carried on. The started safety appraisement works mainly aim at the macroscopical safety control, but also insufficiently are thorough. At present the appraisement methods such as the check table, the marking and so on are still qualitative or half quantificational. The quantificational degree is not high.Aims at the Laochang tin mine's safety appraisement of the Yunnan tin industry group company, the author has carried on the quantificational computation by the method of fuzzy comprehensive appraisement.According to the division of Laochang tin mine's safety appraisement unit, the author has established the appraisable factor collection. By the principle and step of Analytic Hierarchy Process (AHP), the author has obtained each appraisal factor's weight and proven each result was reasonable and feasible. So the author has established the appraisable weight collection. On the base of the division of Laochang tin mine's safety grade and the marking of safety check list, the author has carried on the appraisement to each appraisable factor by the method of subjection function. Than the author has established the appraisement collection. In the known the factor collection, the weight collection and the appraisement collection, the author has carried on two hierarchy fuzzy comprehensive appraisement to the Laochang tin mine's safety in production condition. The appraisement result tallies with the actual situation.Applying the method of fuzzy comprehensive appraisement to carry on the safety appraisement to the large-scale mine, each link all can be provided a complete quantificational computation and obtained a quantificational result. Therefore, the method can unceasingly raise the safety in production management level regarding the mine. At the same time, it can make people not only understand, grasp and adopt the corresponding measure to eliminate the existence of hidden danger in good season, but also reduce and avoid the occurrence of safety accident to come true the normal safety in production. In a word, the method has an important instruction function and practical significance regarding mine.This method's application is very simple. The effect is better. It has a widespread application value when people carries on the safety appraisement to the large-scale mine.
