FIELD: mining machines for underground mining of deposits, particularly, mechanisms and devices of percussive-bursting action on vertical plane of frontal face under protection of powered support. SUBSTANCE: activated plow for mining of kimberlite ores and other minerals with strength up to 8 kN/cm under protection of powered support includes body with mechanism of transfer over powered support units, device for loading and transportation of kimberlite ores at least two hydraulic percussive units with hammers and wedge tools provided with blades. Made in central part of wedge tool is cylindrical piston cavity accommodating piston and anvil engageable with central part of hammer of hydraulic percussive unit. Periphery part of hammer is engageable with circular part of anvil made on end face of wedge tool. Cylindrical piston cavity of wedge tools is communicated through check valve with common chamber installed in plow body. Common chamber is provided with compensator of pressure drop and connected with source of water supply. Blade of wedge tool is separated into two parts. Made over center of wedge tool, between blade parts is jet discharge channel connected by expanding diffuser with cylindrical piston cavity of wedge tool. EFFECT: higher serviceability of wedge tool with blades due to its cooling with water and reduced consumption of energy for breakage of kimberlite ores due to rigid impact with simultaneous use of hydrofrac. 3 dwg
