Abstract: It is difficult to excavate the steeply inclined coal seam, which brings a series of difficult problems to the safety production
of coal seam working face. This paper described in detail the practical experience of W4301 working face passing through
floor steeply inclined uplift. And it described the exposure of abnormal areas in the working face and the problems encountered in
passing through the floor steeply inclined uplift, and illustrated the feasible countermeasures in the period of passing through
steeply inclined uplift from the aspects of "three fine" management, field management, and staff's psychological grasp, which had
certain application value for the excavation of steeply inclined coal seam.

Key words: W4301 working face; steeply inclined coal seam; floor; "three fine" management
