Based on the research needs of the relation between mining stress fields and gas outburst during the process of rock cross-cut coal uncovering

a set of outburst simulation experiment system of rock cross-cut coal uncovering is developed which takes ground stress

gas pressure and coal structure into account comprehensively

while outburst model of rock cross-cut coal uncovering is still on the stage of laboratory research and most don’t comprehensively consider the effect of gas

ground stress and physico-mechanical properties on outburst. To get accurate

objective the experimental effect

the design of key technologies such as main composition structure

function of this experiment system

outburst roadway

quick opening device and nitrogen balance system are introduced. The experiment results reflected the change of stress and gas pressure during outburst in uncovering coal seam using this experiment system. This experiment system provides new technical means for studying on and revealling the change law of mechanism of coal and gas outbursts and ground stress

gas pressure during the process of outburst.
