CHIM法在区域性勘查阶段的应用研究——以新疆金窝子金矿区为例

Application Research on Electrogeochemical Method for Regional Exploration

CH IM法自提出以来,主要应用于矿产勘查的详查及异常查证阶段,其原因主要是CH IM法设备笨重、成本高、工作效率低,而不适合大规模生产的需求。作者通过实验研究,对地电提取方法技术进行了改进——低电压"偶极子"供电方式下的CH IM,该改进方法在广西横县泰富金矿得到了较好的应用效果。在此基础上,在新疆金窝子—210金矿区以500m×500m网度进行了区域性勘查的实验研究,取得了应有的效果,表明地电提取方法进行区域性勘查是有效性的和可行的,改变了以前地电提取法仅适用于详查及异常查证阶段应用的传统方法。

CHIM mainly has been applied in mineral detailed exploration and anomalies identifyication since it was put forward because of heavy equipment, high cost, low working efficiency and not to be suitable for regional exploration. Through testing over the known ore bodies, CHIM has been improved to be low voltage ＇ dipole＇. It showed better application effectiveness in prospecting prediction at the Taifu gold mining area in Heng County, Guangxi. It made improvements on what has already been achieved, so it was applied for regional exploration at 500 m-500 m, and has enabled identification of distinct multi-element anomalies at Jinwozi-210 gold deposit in Xinjiang. It indicated that the improved CHIM is feasible and available for regional exploration, so that the improved CHIM is not only suitable for detailed exploration but also for regional exploration.
