【Abstract】 Applying fuzzy centralization statistical theory, the random and fuz zy indexes in coal mine safety assessment are mathematically analyzed. It improv es the calculating method for weighted value, so that it could more precisely ac cord with the practice. Meanwhile, the reliability of the weighted value obtaine d is analyzed. Exemplified case indicates that the method could overcome the sho rtage of traditional statistical method and make the coal mine safety assessment more practicable and scientific.更多还原
