Abstract. Object of study – vibro-acoustic method mining geophysics, traditionally used to identify of fishweirs and breakings in the marginal zone of the array. Objective – development of equipment that expands the capabilities of the method and improves the efficiency control. Informative assessment of the rock massif parameters underlying the developed equipment - vibration characteristics of its own vibrations. Vibrational excitation is carried out by a single impact. The structure of the apparatus includes hammer, vibration sensor with cable and electronic block. Results are displayed on the three-digit LED display. In order to increase the stability of an electromagnetic vibration sensor configured active. To reduce energy consumption energy-nodes automatically connect for a short time. The design of all components of equipment allows you to perform surveys in remote places. Experimental prototype equipment has been tested at two mines.

Keywords:

 vibro-acoustic control, rock massif, fishweir, breaking, apparatus.
