摘　　要：金属矿产是现代工业的重要支撑,对经济和社会发展具有不可替代的作用。然而,强噪声环境下的矿产勘探面临着诸多挑战,需要创新性的方法和技术来解决。因此,针对强噪声条件下的物探方法组合研究与应用具有重要的实践意义和社会价值。本文以东坪金矿为研究对象,针对其强噪声环境,探讨了大功率时间域谱激发极化法和可控源音频大地电磁法两种物探方法的组合应用。通过对不同方法原理的深入分析和比较,结合实地数据,探讨了其在强噪声环境下的适用性和优势。在此基础上,提出了信噪分离和信息处理的关键技术,为矿产勘探提供了新的思路和方法。实验结果表明,该方法组合在东坪金矿找矿中具有良好的应用效果,为类似环境下的矿产勘探提供了可行性和参考。Metal minerals are the important support of modern industry and play an irreplaceable role in economic and social development.However,mineral exploration under strong noise environment is faced with many challenges,which need innovative methods and technologies to solve.Therefore,the research and application of geophysical exploration method combination under strong noise condition has important practical significance and social value.Taking Dongping Gold Mine as the research object,the combined application of high power time domain spectral induced polarization method and controlled source audio magnetotelluric method is discussed in this paper.Through the in-depth analysis and comparison of the principles of different methods,combined with the field data,the applicability and advantages of these methods in the strong noise environment are discussed.On this basis,the key technologies of signal-noise separation and information processing are proposed,which provide a new idea and method for mineral exploration.The experimental results show that the method combination has a good application effect in the Dongping gold mine,and provides a feasibility and reference for mineral exploration in similar environment.
