Abstract

The invention aims to solve the problem that methods which can distinguish surrounding rock and ore, recognize different types of ore and determine iron ore types on site, in situ, in real time, quickly and efficiently through aerial remote sensing detection of iron ore areas do not exist in the prior art, provides an Anshan type iron ore type determining method based on spectral features and belongs to the technical field of mining geology and remote sensing application. According to the method, visible light-near infrared spectrum tests are conducted on different surrounding rocks and different types of iron ores, the spectral features are analyzed, ore distinguishing models are established according to the spectral features, the ground is scanned by using aerial remote sensing to be divided into small grids, each small grid is scanned by a visible light-near infrared spectroscopy or samples are taken on site and scanned by the visible light-near infrared spectroscopy, and real-timedistinguishing of surrounding rocks and ores, recognition of different types of ores as well as recognition of different types of ores on site and in situ through aerial remote sensing can be realized.

Description

technical field

[0001] The invention belongs to the technical field of mine geology and remote sensing application, in particular to a method for determining the type of iron ore based on spectral features. Background technique

[0002] At present, the classification of iron ore types mainly adopts the methods of on-site sampling and indoor testing. The above-mentioned methods need to use mechanical or manual methods for on-site sampling. , High cost, slow speed, time-consuming and labor-intensive shortcomings. There is also a method of in-situ detection of ore using spectral testing, such as the application of the I-7000 portable mine grade composition analyzer, but this instrument tests the X-ray spectrum, which can only determine the elemental composition of the sample, and cannot test its mineral composition and Determine the ore type.

[0003] Airborne hyperspectral remote sensing is the cutting-edge technology of remote sensing. With its unique technical characterist...
