In the Krasnoyarsk Region, a large number of alluvial deposits are concentrated, the host rocks of which are a clay massif. Of these deposits, the most important minerals, such as alluvial gold and coal, are mined. The most expedient for the development of such deposits under the specified conditions is the use of a jetting. Since the mining enterprises use recycled water supply from settling ponds, when the clay massif is washed away in the pressurized water, suspended fine-grained ground particles accumulate, because of the presence of which the application of the law of changing the momentum of I. Newton\'s calculations becomes impossible and for establishing the dependencies experimental data. This article shows the features of the parameters justification of the model (laboratory installation) for studying the intensity of rocks’ erosion by a pressure jet of a hydro-monitor; the similarity criteria were designed for a laboratory stand at a scale of 1 : 10, which allows to carry out, with sufficient certainty, studies of jetting in a wide range of variable conditions, influence and determine a combination of these factors, which makes it possible to increase the efficiency of mining of mineral resources
