Coal Mine Safety Input And Decision-making Research

Safety production is a topic of universal concern, especially in the coal mine. At this stage. China's safety production situation of coal mine is still grim, accidents of coal mine is always high, serious accidents occurred occasionally. Even though safety input has increased, the probability of accidents is still high, the fundamental reason is that the lack of scientific and rational distribution and not enough decision-making of safety input, at present, study of safety input decision-making theory in our country is still in its infancy. This paper based on analysis of safety input theory, study the safety input decision-making by the relationship among predicted accident probability, safety input and accident loss. The main contents and results are as follows:(1) This thesis concluded basic theory of safety input in coal mines, give some concept a new understanding and expression.(2) Establish the GM (1,1) prediction model of mine staff wounded using gray system theory. In order to improve the precision and accuracy of the predictions, introduces the theory of Markov to correct processing the predicted results of GM (1,1) model, so as to obtain more accurate results.(3) In accordance with the actual production of a mine, elects factors affecting accident casualty rate, analyzis its influencing factors by using gray correlation analysis method, and come to the order of influence factors, to make the mine safe production management department can take stargeted afety measures, reduce accidents, provide the basis for decision-making of safety investment.(4) This thesis is based on MATLAB programming tools, prepared computational model of the accident casualties forecasting and gray relational analysis, and validated by examples, to provide an effective information for subsequent management work in mines.
