Abstract: The auxiliary transportation system of Jiangjiahe mine is rail transportation.In the past, all goaf passageways were maintained by erecting wooden cribs after hydraulic supports were withdrawn, and withdrawal support utilizes a combination of winch and pulley installed in the passage.Through the innovation and application of local ventilation technology of withdrawal passage in equipment withdrawal of Zf215 working face in Jiangjiahe mine and the application of TYH-400 hydraulic support transfer device in the process of support withdrawal, from the aspects of technology introduction, important link operation, construction period analysis and existing problems, this paper proves the advantages of the innovative technology of local ventilation and hydraulic support transfer device in coal face equipment withdrawal, such as simple operation, high safety and economical application, which has also been widely used in support withdrawal of coal face in Jiangjiahe mine with good results.
