Abstract. There is a practical analysis of the most commonly used methods of dewatering of wet finely divided mined rock accomplished. Disadvantages of each of them are listed and a complex method based on three methods of dewatering - vibration, electroosmotic and vacuum combined in a single device, was proposed. A scheme of the device and the way it works, as well as the results of dewatering in a combined method on this device are introduced. Equity participation of each method, depending on the dewatering percentage and the length of transportation on this device, is shown. The obtained results of preliminary studies indicate the effectiveness of the proposed complex method of dewatering and on this basis the prospects for widespread use of the method are concluded.
