Abstract: The direct reading type pressure gauge and digital continuous recording pressure gauge are adopted to monitor the support loading and the change situation of roof pressure in the process of mining of three measurement areas of the 500 m depth fully mechanized working face.Besides that,the stope pressure regularity and the wording characteristics of stents are researched,so the first weighting of main roof of the fully mechanized working face of 500 m depth slowly inclined thick coal seams are not synchronous,intervals on one side of the machine lane is greater than that of on side of the wind lane.The stents and supporting method in this paper can meet the requirements of mining design by analyzing the datas.

Key words: Fully mechanized wording face, Main roof, Mine pressure, Interval
