Simulation experiments of coal and gas delay outburst in rock cross-cut coal uncovering were done under the condition of fixed vertical stress or horizontal stress with a large-scale test device for simulating the coal and gas outburst and the outburst port closed by a mixing-material of coal powder and gypsum-simulated hard coal. The results show that the relationship of critical gas pressure and horizontal stress at delay outburst is exponential and reversely changes under fixed vertical stress,but relati...
