Evaluation and Application of Coal Mine Electromechanical Safety Based on Entropy Weight Matter-element Extension Model
In order to objectively evaluate the safety status of coal mine electromechanical equipment,the safety evaluation index system of coal mine electromechanical equipment is constructed from four as-pects of human,machine,management and environment.The entropy weight method is used to calculate and allocate the weight of each index.Combined with the extension theory,the classical domain,the section domain and the matter element to be evaluated are constructed,and the correlation degree of computer elec-trical safety level is established.The evaluation model of electromechanical safety status is established and applied to the electromechanical safety evaluation of a coal mine.The results show that the evaluation grade of the electromechanical safety status of the coal mine to be evaluated is'safer',which is consistent with the actual situation,and the evaluation results have certain guiding significance for the safety management of coal mine electromechanical equipment.This shows that the entropy matter-element extension model has cer-tain practicability and can objectively evaluate the electromechanical safety status of coal mines.
