The invention discloses a
simulation test
system of
coal-gas outburst during rock cross-
cut coal uncovering, comprising a box provided with an opening at the top thereof, wherein the opening is equipped with a loading steel plate; a top plate and a bottom plate are paved in a
closed cavity; a
coal layer is paved between the top plate and the bottom plate; a
slant angle is formed between the coal layer and the horizontal plane; an outburst
simulation roadway is stretched in the bottom plate till being intersected with the coal layer; a notch attached to the coal layer is arranged at the intersection of the outburst
simulation roadway; a diaphragm is arranged at the notch; an outburst opening and a gas balance opening are arranged at a part of outburst simulation roadway, which is exposed out of the box; the outburst opening is provided with a quick-opening seal structure; the gas balance opening is communicated with an air pressure tank; surface
inflatable structures are respectively arranged on the contact surface of the coal layer and the top plate as well as the contact surface of the coal layer and the bottom plate; and the surface
inflatable structures are communicated with a
gas pressure tank. According to the invention, a mechanical release-
diaphragm rupture method is adopted to ensure that the whole-
process simulation of the coal-gas outburst during the rock cross-
cut coal uncovering is realized.
