N2  - To overcome the disadvantage of existing fast airtight devices, a latest-model airbag type fast airtight device was devised. Operating principle, structure and installation procedure of the device are presented in detail. Based on related technical parameters of return airway section on working face 15108 of Shi Gang Coal Mine, ANSYS analysis model was created. With a certain pressure and temperature condition, stress and strain in x, y and z directions of the airbag were calculated and the results proved the feasibility of the design proposal. Through field test and analysis of experiment results, the advantage and disadvantage of the latest-model fast airtight device were summarized, in hope to offer some inspiration to the development of airbag type mine airtight device.<p />
