FIELD: mining industry. SUBSTANCE: injection device is intended for injecting consolidating solution into mass of rock materials for its strengthening. Injection device has vessels containing components of consolidating solution, pipelines, mixer, hermetic sealing unit, and multiple-piston pump with frame and hydraulic cylinders which are pivotally connected to frame and are rigidly connected to each other by means of cross-member. Hydraulic cylinders are provided with individual crank mechanisms of pump drive, and with levers having cranks which are interlocked by means of common shaft. Cross-member is connected with regulator of capacity of hydraulic cylinders through their synchronous turning. Aforesaid embodiment widens field of application of injection device because it allows for injecting components of consolidating solution of any kind and in required proportions. EFFECT: higher efficiency.
