摘要
利用FLAC3D软件模拟不同顶底柱厚度的采场,分析了顶底柱厚度与顶板、顶柱位移的关系,并从顶底柱厚度变化对塑性区影响进行了比较,得出了亢马矿安全的顶底柱厚度。
Mining stope of different roof and bottom pillar thickness are simulated by FLAC 3D software,the relationship between roof and bottom pillar thickness and displacement of roof and top pillar are analyzed,comparison of the influence to plastic zone are done from the change of roof and bottom pillar thickness,safe roof and bottom pillar thickness of Kangma mine is obtained.
