地质信息约束下的三维密度填图技术研究

Study on Density of 3d Mapping Technology under Geological Information Constraints

重力和磁法勘测在矿产勘探中应用极其广泛且成本相对较低,该技术能够在隐伏矿定位及靶区优选中发挥巨大的作用。在实际操作过程中由于重磁解释具有多解性,故在采用重磁解释中应采取相应的措施以降低其多解性,通常采用的措施是以地质约束反演。以三维密度填图技术研究为最终目标,通过模型试验对比是否存在约束情况下的反演效果,结果显示采用地质信息约束的三维密度填图技术能够有效发现深部矿产。

Gravity and magnetic method exploration in mining was widely used with relatively low cost, the technology played an important role in buried mine positioning and target section optimization. Magnetic interpretation was with multiplicity of solution in practice, corresponding measures were taken to reduce the multiplicity of solution, geological limiting inverting was commonly adopted. 3 d density mapping technology research was taken as ultimate goal, through mold experiment to see if there was inversion effect under constraints, the result showed that 3 d density mapping technology with geological information constraints could explore deep mining.
