Аннотация: It is considered to be the most effective to use water jetting for placer deposits, composed of clay wall rock. To increase its production, various constructive and technological methods are possible to apply. For the breaking performance increasing, the use of a special device has been proposed, which ensures the ejection of solid abrasive particles into the hydro monitor barrel. The use of this device allows increasing the performance of the hydraulic breaking of the mined rock mass by 4.8-7.4 times. The use of the technology is most effective when applying a mining method with minor or side mine face at an angle of about 35° between the mine face and the jetting axis, but does not exclude the use of other mining methods. © 2020.
