从离子吸附型稀土矿开采过程中沉淀池状态及其空间分布关系入手,构建了面向对象的稀土开采高分遥感影像识别方法,并采用定南县岭北稀土矿区的Pleiades卫星遥感影像和寻乌县河岭稀土矿区航拍遥感影像对该方法进行检验。结果表明,卫星影像和航拍影像对于稀土矿点开采中的沉淀池识别精度分别达到94.17%和90.03%,具有较高准确度。该方法能够用于离子吸附型稀土矿区的开采过程监测,为矿区的非法稀土矿区非法开采快速、准确、动态监测提供了技术手段。
Starting from the relationship between sedimentation tank state and its spatial distribution during ion-adsorption rare earth mining process, an object-oriented high-resolution remote sensing image recognition method for rare earth mining was established. Pleiades satellite remote sensing images and XUOYU This method is tested by aerial remote sensing images of Helehe rare earth mine in County. The results show that the recognition accuracy of satellite images and aerial images for the sedimentation tanks in the exploitation of rare earth mines reaches 94.17% and 90.03%, respectively, with high accuracy. The method can be used for monitoring the mining process of ion-adsorbed rare earth mining area and provides technical measures for the rapid, accurate and dynamic monitoring of illegal mining of illegal rare earth mines in the mining area.
