THE STUDY ON CORRELATION BETWEEN THE GEOMAGNETIC DISTURBANCE AND INDUSTRIAL ACCIDENTS
Li Qingxuan;Huang Haoping(Department of Geophysics)
Some significant conclusions can be got from the correlation analysisbetween industrial accidents and geomagnetic disturbance. Such as the frequency ofindustrial accidents is directly proportional (correlation)to the magnetic field index. Thecorrelation coefficient will be 0.93 when the index is more than 30. The frequency ofindustrial accidents will increase from 0.7 to 1.85 as the magnetic field index changesfrom 30 to 200,and the highest frequency in the day with intense magnetic disturbance is2; 67 times as much as that of general day. Geomagnetic field is an importantenvironmental factor. Persons organization and acts will be effected seriously by thechange of geomagnetic field when the change exceeds the range that one can adjust himselfto adapt t.。Thus industrial accident will increase obviously in the period.
