Study Of The Appraisal Method Of The Potential Safety Hazard Of Fully Mechanized Mining Face

This paper adopts the potential safety hazard of fully mechanized mining face as the research object in the pit with the mine. Our studies are based on the knowledge of safety management and systematic scientific theory, and we consult a lot of experts and investigate many times. System of appraising models of the potential safety hazard of fully mechanized mining face is founded. Concrete content includes:This paper uses analytic approach systematically combining together man, machine, environment and management. The artificial hidden danger, the environmental hidden danger, hidden danger of equipment in the working faces and manages, carrying on comprehensively to the colliery in the pit, are systematic analyzed. And studying different of influence factors of hidden dangers deeply, which lay a solid foundation to the foundations of the appraise index systems of potential safety hazards of fully mechanized mining face.The security system of fully mechanized mining face has the characteristics, such as fuzzy quality, , non-linear, dynamic quality etc, and people, machine, environment, management in charge of four systems have nothing in common with each other. Influence factors of the environmental hidden danger of fully mechanized mining face are many for the quantitative index. With artificial neural network method, making use of data of the hidden danger state, this paper determines the weight of the appraise index by preventing determining the deficiency of the weight. On the basis of this, set up the comprehensive appraisal model of the environmental hidden danger of working face. In accordance with the artificial hidden danger of fully mechanized mining face has more of qualitative appraisal index, and it is difficult to determine the value of those appraisal index., then set up the comprehensive appraisal model based on neural network theory. Considering the reality of the managing hidden danger of fully mechanized mining face, the paper set up a gray and fuzzy comprehensive evaluation model of the managing hidden danger of fully mechanized mining face. Set up the comprehensive appraisal model which adopts the hidden danger of equipment of working face based on fuzzy mathematics; In order to change the deficiencies of either determining weight value objectively or determining weight value subjective at present, therefore this paper utilizes the advantages of them, set up comprehensive evaluation model of hidden danger of fully mechanized mining face on the base of the potential safety hazard appraises of man, machine, environment and management.Combining the actual states of fully mechanized mining face and consult colliery" disobey at three" situation counting and safe information material, In addition, and consulting ore expert modestly, we carry on actual appraisal in the potential safety hazard of working face and receive better result.
