大倾角煤层 pitched seam ; deep inclined seam
而放煤漏斗轮廓受煤层倾角影响不大。
The coal seam dip Angle has little effect on the caving funnel.
在诸多的影响因素中，煤层倾角是控制“三带”高度的最主要因素。
Among several factors, dip Angle of coal seam is the most important factor affecting the height of the three zones.
得出了煤层倾角、水平分段高度对顶板变形的影响关系曲线，同时，给出了顶板破断的判据。
Relationship curves between seam dip Angle, horizontal section height and roof deformation are derived, at the seam time, the criterion of failure is given in this paper.
