药园山铜矿-440米以下矿体地质特征浅析

Analysis on geological characteristics ore body below-440m in Yaoyuanshan Copper Mine

药园山铜矿位于长江中下游多金属成矿带铜陵矿集区的凤凰山矿田,为典型的矽卡岩型矿床。目前,矿山开采由浅部转向深部,为提高矿体控制程度及地质研究程度,对-440m以下矿体赋存情况进行了加密控制。矿床深部的地质特征、成矿条件得到了更深入的认识和研究。本文以-440m以下探矿资料为基础,结合电法、化探、地质力学等研究成果,对深部矿体特征进行分析和讨论。

The Yaoyuanshan Copper Mine is located in the Fenghuangshan orefield of the Tongling ore-concentration zone of the polymetallic metallogenic belt in the middle and lower reaches of the Yangtze River. It is a typical skarn deposit. At present, the mining from the shallow part to the deep part, in order to improve the degree of ore control and geological research, the occurrence of ore bodies below -440m is encrypted. The geological characteristics and metallogenic conditions in the deep part of the deposit have been further understood and studied. Based on the exploration data below -440m, this paper analyzes and discusses the characteristics of deep ore bodies based on the research results of electric method, geochemical exploration and geomechanics.
