Abstract: There are a series of on-site management problems in the process of fully mechanized mining face with high mining height, such as easy frame falling, scraper conveyor moving up and down, roof control difficult, maintenance equipment difficult and so on.Taking the 7 m large mining height fully mechanized working face in Bulianta Coal Mine as an example, this paper introduces engineering quality management, roof control method and equipment fine maintenance method in the process of working face mining.For similar geological conditions of large mining height fully mechanized mining face mining site management to provide a certain reference.
