Abstract: With the micro structure, mercury pressurized test, high pressure isothermy adsorption test and gas outburst parameter and other test & analysis on the nine different type structure coal samples and in-situ structure coal samples, the gas features and the outburst control function of the different type structure coal were studied.The results showed that the structure stress function at the development parts of the broken coal, palea coal and mylontic coal would be obvious and would be t he coal and gas outburst occurred zone.The porosity and porous volume of coal would be positively related to the deformation degree of the structure coal.Before the C oal crushed, the specific surface area of coal would be steadily increased and then could be reduced.The max adsorption value would be controlled by the specific surf ace area obviously.With the structure coal deformation degree increased, the sturdiness coefficient of the coal would be steadily reduced.Before the palea coal, the gas diffusing initial velocity would be steadily increased and would be rapidly decreased at the mylontic coal stage.The porous volume and specific surface area both would be passively related to the outburst comprehensive index K.The relationship between the max adsorption value to each outburst parameters would not be obvious.
