Abstract
Aimed at the exposed problems of ZF6000/17.5/28 type hydraulic support applied at the fully mechanized caving face,in three soft coal seam,the technology reform is in progress.The practice proves that the reformed hyolraulic supports suit for the geologic condition of three soft coal seam.
