METHOD OF DEVELOPING RESERVES OF SOLID MINERALS IN RIVER BEDS Russian patent published in 2024 - IPC E21C50/00 E21C41/26 E02D29/63 E02B3/00 

FIELD: mining.

SUBSTANCE: invention relates to development of solid mineral resources by open method in river beds. According to the described technology, water of small and medium rivers is raised, in which the main reserves of the deposit are located under the river bed, and it is impossible to develop them using known methods. Method includes diversion of river water for development of reserves, which is carried out in warm season with the help of waterproof fabric, forming a water conduit from it. Water of the river is passed through the water conduit and laid depending on the terrain so that the river water upstream can freely enter the water conduit and continue to flow by gravity at the required minimum slope of the water conduit. At the same time the section of the water conduit remains in the river bed, and on the water-free part of the river bed, the reserves are developed. Then water conduit is released from water and transferred to unworked part of river bed to continue development of reserves. When creating a water conduit, the waterproof fabric is laid in the river bed so that its lateral edges lie on different river banks while observing the bends of the river bed on both river banks. After laying the water conduit and filling it with water, a water conduit with water is lifted above the river bed, curved, repeating the shape of the river bed, or straightened.

EFFECT: simplifying the method by excluding operations when using additional devices for catching and redistributing water of the river bed and increasing the efficiency of extraction of solid minerals in river beds.
