摘要:

中国作为全球最大的黄金生产国和消费国之一,金矿资源对外依存度高,加大勘查开发力度至关重要。星星峡东山地区所在的东天山作为新疆重要矿产资源基地,金及多金属成矿潜力显著。基于矿产地质调查,以星星峡东山地区为研究对象,通过野外勘查、探槽工程及地球化学分析,新发现红星山金矿点、东铅炉子铅矿床及4处铜矿点(转井、转井东、东山、东山东)。研究表明,星星峡东山地区金成矿类型可能是斑岩型成矿系统的一部分,即浅成低温热液型;铜成矿类型可能是岩浆热液脉型;新发现的铅矿床可能是钼成矿系统的远端端元。星星峡东山地区具有金、钼、钨、锡、铜勘查潜力,同时可能存在斑岩型钨-锡及钼矿。

Abstract:

The Jiama copper polymetallic mine, one of China’s highest⁃altitude and largest porphyry coppermines, faces dual threats of concealed water⁃conducting structures and karst fissure water as mining depths exceed4 300 m. This study optimizes the application of dynamic transient electromagnetic(TEM)detection technology for themine and systematically develops precise detection methods for concealed water hazards. By analyzing the characteristicsof concealed water hazards, forward models of typical aquifers were established, and 3D numerical simulations wereconducted to investigate induced electric field propagation and response characteristics. The dynamic TEM imagingalgorithm was improved to achieve high⁃precision, real⁃time interpretation of underground TEM signals. Parameter testsinvolving different coil configurations, transmitting currents, stacking numbers, and detection frequencies were carriedout to determine the optimal detection parameters for the Jiama copper polymetallic mine. Field tests demonstrated thatthe technology enabled accurate extraction of low⁃resistivity anomalies(apparent resistivity <6 Ω·m)within high⁃resistivitysurrounding rock backgrounds, rapidly locating concealed water hazards. The results provide a robust geological safeguardfor safemining operations at Jiama copper polymetallicmine and open new avenues for water hazard prevention and control.
