Study On Water Inrush Safety Evaluation And Countermeasures In Chinacoal HZ Mine

Safety is always the most important core problems of the coal enterprises,including water inrush and gas explosion are the two main types of serious accidents,accidents often caused huge economic losses and casualties.Therefore,it is of great significance to comprehensively analyze the influence factors of coal mine water inrush safety and to construct the evaluation system of water inrush safety,which is of great significance for the prevention and reduction of water inrush accidents.Based on the topic of water inrush safety,this paper uses the method of fuzzy comprehensive evaluation and analytic hierarchy process to evaluate the water inrush safety:Firstly,a comprehensive safety evaluation model based on fuzzy analytic hierarchy process is built.Considering the coal mine production system and the complex environment,through in-depth analysis of the "human machine environment management" four factors of water inrush safety,to identify hazards,five major factors that affect the safety of the coal mine water inrush and twenty-one basic indicators.On this basis,a hierarchical multi-level coal mine water inrush safety evaluation index system,we construct the comprehensive safety assessment of comprehensive application of coal mine water inrush model,and gives the detailed calculation methods and steps.Secondly,the water inrush safety evaluation model is applied to the coal mine HZ ".On the basis of investigation and expert scoring field,the evaluation indexes for quantitative data processing,a comprehensive evaluation of quantitative data into the constructed model,calculated by the mathematical method of water inrush safety evaluation in coal mine grade empirical HZ coal mine ",verifies the feasibility and effectiveness of the evaluation model.Finally,according to the analysis of the conclusion of the evaluation,and according to the actual situation,the management from the management measures,technical measures and facilities in three aspects of "disaster prevention of water inrush are coal HZ coal mine" the specific measures and methods,further validation of the method used in coal mine water inrush safety evaluation in the field of theoretical significance and promotion.
