摘　　要：应用光弹性模拟实验方法,对条带开采煤层顶底板及条带煤柱的应力分布规律进行了深入的研究,得出了随着煤层倾角的变化条带采场应力变化及应力集中转移规律.By using optics-elastic stimulated experiments.this paper studies the stress distribution in the roof.floor and coal pillar of strip mining.It attains the stress variation and the transferring iaws of stress concentration with the change of coal seam dip angle.This paper provides the theoretical gist for reasonable arrangement and the coal pillar stability study of strip mining.
