Geological Statistics Study on Grade Variations in Ore Body 1 of the Macheng Iron Deposit, East Hebei, China

Abstract:

Variation function as a main analytical tool is used for geological statistic study on grade variation characteristics of different segments in ore body 1 of the Macheng iron deposit (MID). The results indicate that the main ore body is bounded with-500m elevation, the upper grade change meets void effect, the lower grade change accords with the characteristics of spheroidal variation function and the upper change is smaller than the lower one in the general grade change. Based on fitting the variation functions of separate grade changes in different areas, the upper area and the lower area, and combined with the parameter values of each variation function, it is thought that production exploration distances that are suitable for the upper and lower ore bodies are respectively 35m and 30m in the vertical direction.
