伪倾斜长壁俯采进刀方式与放顶煤顺序分析

Analysis on Caving Order and Oblique Longwall Retreating with Underhand Feed Model

分析比较厚度为 5～ 7m的煤层倾斜长壁在采用综放工艺俯采推进时 ,选择不同的进刀方式、不同的放煤顺序的回采效果。指出两端进刀、中部进刀与不同放煤顺序的组合方式对工作面坡度、煤层倾角。

This paper analyses when 5～7m coal seam inclined longwall is mined with underhand of sub-level caving craft,it selects defferent way of feed and defferent caving order.It points out bothsides feed,middle feed and defferent order,this combination way hewe adaptability to slope of workface,dip angle of coal seam and length of workface.
