FIELD: mining industry, possible use for hydraulic destruction of mineral resources.
SUBSTANCE: lightened hydro-monitor includes supply water duct with supporting elements, joint and turning channels, rectilinear shaft with adapter and mouthpiece, vertical and horizontal hydro-cylinders with control system, expanding diffuser is mounted between rotary channel and rectilinear shaft, in channel of which impingement plate is mounted, which impingement plate is positioned in zone of maximal speed of distribution of flow across channel cross-section, which flow enters diffuser, external surface of impingement plate and internal surface of diffuser are made with streamline contour.
EFFECT: decreased mass of hydro-monitor.
