Abstract: Through the research of working face equipment moving engineering in Tongxin Mine super thick coal seam under the condition of single mining full-seam low caving mining technology, we apply support retracement crane to solve the problem of hydraulic support in long retreat, implement safe and rapid working face comprehensive mechanization of the relocation process. Application result shows that the technology can significantly improve the efficiency of relocation, to ensure the safety of operation; the process of production and application effect is good.
