Laboratory research of vibration impact parameters on the coal seam through host rocks

Abstract

On the basis of mechanized roof supports, the hydraulic systems of vibrators operating as compact vibrators for controlling the condition of the coal and rock mass through host rocks are selected and refined. Bench testing of vibrator systems operating in continuous and pulsed modes with automatic control were held. The basic parameters of the systems of vibrators are established, and the fundamental possibility of their work in the working face of gas-dangerous mines was proved.
