改进地电化学方法在矿区勘查中的试验与应用

CHIM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CHIM法设备笨重、成本高、工作效率低，不适合大规模生产的需求。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CHIM。该改进方法在广西横县泰富金矿得到了较好的应用效果，在新疆金窝子-210金矿区以500m×500m 的网度进行了普查阶段的实验研究，也取得了应有的效果，表明地电提取方法不仅适用于矿产勘查的详查及异常查证阶段，而且可有效地应用于普查阶段。

Experiment and application of improved CHIM in mineral exploration

Ever since CHIM has came into being, it's mainly used in detailed exploration and anomaly validation. Constrained by heavy equipment, high cost and low efficiency, CHIM is not suitable for large-scale exploration. Through several experimental attempts, CHIM has been innovated into a power supply under low voltage "dipole". Satisfactory application has been achieved in Taifu gold mine in Heng County, Guangxi with improved CHIM. Also it was adopted experimentally during general prospecting at 500 m × 500 m spacing at Jinwozi-210 gold deposit in Xinjiang. It indicated that the improved CHIM is feasible and available in search for minerals. In conclusion, improved CHIM can be not only used for detailed exploration and mineralization validation but also in general prospecting effectively.
