ABSTRACT
In order to explore the new technology of long-distance filling reclamation with Yellow River sediments, 17 mining subsidence in the Northern of Jining city, Shandong province, are used as the research object to introduce the technology. The technology includes 3 parts: predicting mining subsidence, extracting and long-distance transporting Yellow River sediments, and reclaiming subsidence land to be the cultivated land with filing measures. Three sediment fields are laid in the diversion gate of Chengai. Suitable sediments-extracting equipment and pipelines are selected to extract and transport the sediments. Four pump stations are set on the competent route. Different filling methods are chosen according to the condition of the subsidence land. Finally, making the planning of farmland, farmland water conservancy and field road and making the design of shelter forest, to establish a complete farmland ecological system.
