Abstract: We introduces some of past physical testing methods and theoretical achievement of coal and gas outburst. It finds that physical simulation test contains five different tests, like simulation test of gas pressure membrane rupture outburst, slow interference outburst simulation test, sudden ignited pressure simulation test, instantaneous pressure relief outburst simulation test, and indirect outburst simulation test. Furthermore, seepage test moves from singular factor into more multi factors analysis, and it finds out laws of those factors which affect seepage variation. At present, these tests are considered as static outburst ones, rather than dynamic outburst tests. These tests never involve gas seepage property under mechanical vibration. None of them study the seepage law prior or after the outburst. Nor do they analyze the relation among physical property of coal, gas absorption and adsorption, deformation property and outburst damage property. Moreover, these tests never contain vibration which affects coal intensity, absorption volume, seepage and outburst.
