摘要
运用数值模拟的方法,采用FLAC3D程序对窄煤柱沿空巷道围岩的应力场和位移场进行了计算,确定合理的煤柱的宽度,并根据掘进与回采期间的实测结果分析,选择5m煤柱作为窄煤柱护巷能够保证巷道使用安全,为窄煤柱沿空巷道合理煤柱的留设提供一定的参考。
This paper applied numerical simulation software-FLAC3D to calculating stress field and displacement field of surrounding rock of roadway driven along gob for rational pillar width. It presented 5m pillar was rational for roadway safety by analysis of observation data in mining and roadway driving, which was reference to narrow pillar design for roadway driven along gob.
