Abstract: To study the goaf gas control model of top coal caving after the collapse of mining-induced rock, based on the importance of the development laws of mining-induced rock fractures, in the view of E1310 fully-mechanized caving working face, the distribution of porosity and permeability of mining-induced rock was studied by using MATLAB. The most reasonable goaf gas control mode including 4 kinds of ventilation way, 6 extraction positions of high drainage roadway and 41 kinds of extraction negative pressure was studied by the numeral simulation software of FLUENT. The results show that the gas concentration at upper corner is 3% when it uses "Y" ventilation way. The gas concentration at upper corner dropped to 0.5% when high drainage roadway layouts in the 50 m away from floor and 50 m away from return airway. Gas is not overrun and the oxygen concentration is 22% at working face when the extraction negative pressure is 1.9 MPa.
