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、工作面长度三种因素的适应性
Analysis and comparison of coal mining inclined wall with thickness of 5 ~ 7m When using the fully mechanized top coal caving mining technology, different feeding methods and different coal caving sequences are selected. It is pointed out that the combination of the two-end infeed, central infeed and different caving sequence adapts to the three factors of face gradient, coal seam dip and working face length
