Abstract:

This paper analyzed the variety trend and characteristics of the thickness and the grade of main orebody in Jiaojia gold mine, and made the quantification to its change. The variety coefficient of thickness is 31.7% - 123.7% , namely " comparative unstable" ; and the variety coefficient of grade is smaller than 93% , and general is 27.5% - 85.3% , namely the distributing of useful component is " uniformity". The variety tendency of the thickness and the grade is big in direction of tilt than strike slightly.

Key words: Orebody, Coefficient of variation, Mathematics analysis
