A pulse hydraulic monitor comprises two barrels for alternately directing a pulsating jet of liquid onto a target, a valve means for dividing the flow of liquid, having an inlet for a hydraulic liquid, and two outlets for delivering the same into the barrels, and pulse-forming means. The pulse-forming means includes a through hollow enclosure, a separating member, two limit stops of the separating member, means for retarding the motion of the separating member. The through hollow enclosure is in hydraulical relationship with the barrels and the separating member is movable between two end positions relative the barrels so as to take one of these two end positions for forming a pulse when the pressure of the hydraulic liquid flowing in the corresponding barrel assumes a predetermined value. The means for retarding the motion of the separating member is made in the form of a pipe filled with the hydraulic liquid under the pressure produced by a pressure source, or of a cylindrical compression spring, or of a sleeve closed by a membrane and filled with a compressed gas. The separating member operates as a result of the liquid pressure assuming a predetermined value in the corresponding barrel only after the pressure in said barrel is incresed to a desired value.

The coal mining combine has a crawler carriage with a driving mechanism supporting a bed plate with a turntable on which an arrow-like actuator with a motor for rotating it and a bit are hinged. The hollow body of the actuator contains a built-in monitor. Hydraulic cylinders which are used for moving the actuator and the monitor's barrel are provided. Manifolds are used for supplying water to the monitor and to the actuator. In accordance with the invention, a channel is made in the supporting bed plate. This channel is a hydraulic shock acceleration tubing whose sections are located one above another in at least two rows. A pneumohydraulic accumulator communicating with the water supply source is connected to the channel's inlet, while an oscillator, included in the network for supplying water to the monitor, is connected to the channel's outlet.
