Abstract：This paper gave a description of the design and development process of a 3D similar simulation model system for mine gob air leakage in order to study the air leakage law in the gob. A 3D strata model was built up by using the similar strata and in this strata model, a 3D gob model by natural caving was formed by adopting a unique mining system. Acoustic emission technology and precision gas detection system were used to monitor the process of the model formation and ventilation. The characteristics, experiment method and actual application of each system were discussed. The application showed that this model could really reproduce the rock pressure and porosity distribution in the mine gob, the experiment process was similar to the actual mining environment, and the obtained data can be used for studying the air leakage law in the gob.
