为了改善中深部有色金属矿产资源的勘探效果,对激电测深多通道观测方法及反演成像技术展开研究。首先,提出4种多通道观测方法,包括单边和双边供电的三极和四极模式。然后,给出最小二乘意义下激电测深最大光滑约束反演方法,编制反演程序。通过对模拟和反演结果进行分析,双边供电的三极观测方法勘探效果最佳,但野外工作强度较大;单边供电的三极和四极观测方法的勘探结果较好,从探测效果及野外施工的角度考虑,它们更适合于实际应用;双边供电的四极观测方法不适于探测产状较陡立的脉状矿体。
In order to improve the exploration results of non-ferrous metal mineral resources in the deep and deep, the multi-channel observation method and the inversion imaging technique of the electro-acoustic sounding are studied. First, four multi-channel observations are proposed, including the triode and quadrupole modes of unilateral and bilateral power supply. Then, the maximum smooth constraint inversion method for the bathymetry in the sense of least square is given and the inversion program is compiled. Through the analysis of simulation and inversion results, the bipolar power supply method has the best prospecting effect but the field work intensity is great. The three-pole and quadrupole methods of unilateral power supply have better exploration results, From the perspective of field construction, they are more suitable for practical application. The quadrupole observation method of bilateral power supply is not suitable for detecting the steep-echelon vein-shaped ore bodies.
