摘　　要：本文采用辅助面积法和弹塑性极限平衡理论法计算了大柳塔煤矿大采高综采工作面区段煤柱宽度,得出现有的20m区段煤柱宽度可以减少至16m的结论,结合分析锚杆支护对煤体强度的作用机理,论证了“窄煤柱”锚网支护的合理性,可进一步减小区段煤柱宽度。It calculates the width of the section coal pillar of large cutting height face in Daliuta coal mine and draws a conclusion that the current width(20m)can be reduced to 16m by adopting auxiliary area method and elastic-plastic limit equilibrium theory.It also demonstrates rationality of anchor network support for the narrow coal pillar,which can further reduce the width of section coal pillar by analyzing the function mechanism of anchor rod support for coal body strength.

关 键 词：大采高综采工作面 区段煤柱 锚网支护理论
