Abstract
The magnitudes of the relationship between the conditions of the weekly weather matrix and the numbers of mining accidents during a one-year period were determined by multivariate analyses. Measures of means and variations in temperature, humidity, sunshine hours, windspeed, precipitation, barometric pressure, and geomagnetic activity per week were selected. The analyses were dominated by single variables. Whereas medical aid accidents tended to increase as the barometric pressure decreased, first aid accidents increased as the geomagnetic variation increased. The barometric pressure changes accommodated 16% of the variance in the numbers of medical accidents while geomagnetic variations accommodated 23% of the variance in first-aid accidents.
