Defining the Main Parameters of Hydro-Dumping at Open Pits

Abstract

Currently, the mining industry faces the problem of intensifying extraction and processing of mineral raw materials with minimal costs forthe development of mineral deposits. It should be noted that the greatest degree of technological processes mechanization in the development of deposits is achieved by means of hydromechanization. For example, in the development of placer deposits by the open pit method, the application of hydromechanization, with the appropriate parameters, ensures the necessary disintegration of clay inclusions at minimal cost. It allows solving the issues of the most complete extraction of a useful component. Increasing the effectiveness of the use of a hydromechanized method is favored by the use of bulldozers, excavators and other open pit mining machinery for loosening the rocks. With a rational design of the circulating water supply systems, hydromechanization means using the methods of limited waterconsumption. The hydraulic method for mining mineral deposits is taken to the leading place from the point of view of environmental protection. At thesame time, the greatest environmental effect is achieved under the condition of an accurate calculation of the main parameters of hydro-dumps.
