2、 （Signature） Instructor : Zhang Jianrang （Signature） Wei Yinshang （Signature） ABSTRACT Coal mine is the place where

3、 safety accidents often happen. Gas explosion, coal spontaneous combustion, coal dust explosion, roof accidents and flooding accidents, were great proportion in coal mine accidents. Thus, assessment on the hazards of coa

4、l mine was an urgent problem in safety management that need resolvement. In this paper, the current development and safety situation of coal industry in china was analyzed, the significance and basic content of the hazar

5、d risk assessment was illustrated, and the research status on risk assessment at home and abroad was briefly introduced. Firstly, based on three kinds of hazard theory, the mechanism and effect factors of causing mine ha

6、zards(gas explosion, coal spontaneous combustion, coal dust explosion, roof accidents and flooding accidents) was discussed, and three kinds of hazards on coal mine is analyzed theoretically, on the basis of theoretical

7、analysis, models of the colliery accident hazard effect factors were established. Secondly, aim to the five common kinds of accidents(gas explosion, coal-selfignition, coal dust explosion, roof accidents, flooding accide

8、nts), combined with on-site conditions, from the point of the mechanism and effect factors of hazard theory, typical indexes were indentified, index system of assessment models of hazard root were properly built. Newly,

9、through the illustration of risk assessment methods, by using expert qusetionaire method and analytic hierachy process, the values of indexes was confirmed. Risk assessment on the hazards of the five kinds of accidents

10、which often happen on coal mine were analyzed and studied by using the method of fuzzy comprehensive evaluation. Eventually, in the application for on-site conditions, depending on interrelated technical standards and re
