Abstract：As the corner region between open-off and mine field boundary can't be mined by fully mechanized mining,resources in the area was to be wasted.In order to further improve the recovery rate of resources,the technology of open-off oblique adjustment was applied in Daliuta Coal Mine,to recover the boundary coal behind open-off to the utmost.Besides taking special design of relevant roadways,in the oblique adjustment technology,the direction adjustment process should also be taken during initial mining of working face.In this paper,the open-off oblique adjustment design and direction adjustment process in initial mining of fully mechanized working face are introduced.
