Abstract: The moving face of fully mechanized coal mining face is an important link in mine production connection. The selection of construction technology determines the construction progress and construction safety.In view of the moving problem of 50102 working face in haohaogou coal mine, according to the principle of system analysis, through finding the key link and grasping the key link, starting with the 2 aspects of the hydraulic support handling and handling equipment, the single channel double wing retracting process is studied and optimized, which improves the fully mechanized mining and moving speed, reaching the advanced level in China. Better economic and social benefits have been made.
