缓倾斜煤层开采侧向支承压力分布特征模拟研究

摘要

为全面了解缓倾斜煤层开采后围岩应力分布规律,运用相似材料模拟方法.以某矿综采工作面的实际工程地质情况为依据,分析了采场两侧向的支承压力分布情况及应力集中程度、应力峰值距煤壁的距离、支承压力的影响范围等方面,为该矿采区巷道的合理位置布置提供参考价值.%In order to completely study on the characteristics of stress distribution on mining in gently inclined seams, by the means of similar simulation, a mechanized face in some mine with the actual engineering geology as the basis, abutment pressure distribution and concentration degreed, the distance between peak stress and coal face, the influence circle of side abutment pressure and so on in both sides of stope are analysis. The reference value is provided for the rational arrangement of district roadways in this mine.
