硅钙面理论在马坑铁矿区的找矿实践

Prospecting Practice of Silica-Calcium Surface Theory in Makeng Iron Mine Area

本文以马坑铁矿78-80线(18m~90m分段)、东区84线以东(233m~300m分段)为研究对象,利用硅钙面控矿理论,系统收集现有地质资料,通过钻探工程手段,按60m×30m勘查工程网度获得探明+控制资源量266.17万吨,地质品位37.25%,为后期在硅钙面位置深部边部找矿提供了理论依据。

This paper takes the 78-80 line(18 m~90 m section)of Makeng Iron Mine and the east of the 84 line(233 m~300 m section)of the east area as the research objects,uses the theory of silico-calcium surface ore control,systematically collects the existing geological data,and through drilling engineering means,obtains 2.6617 million tons of proved controlled resources according to the 60 m×30 m exploration engineering network,with a geological grade of 37.25%,which provides a theoretical basis for later prospecting in the deep edge of the silico-calcium surface.
