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因素,为该矿采区巷道的合理位置布置提供参考价值。
To thoroughly understand the surrounding rock pressure distribution in gently inclined coal seam after the mining,similar material simulation was used to analyze the supporting stress distribution in both sides,stress concentration,distance between peak stress and walls,and influential range of abutment pressure on the basis of engineering geology condition,which is valuable for the rational roadway layout.
