摘　　要："三下"煤炭资源普遍采用条带开采,但条带开采结束后,有近60%的煤炭以煤柱的方式被永久遗留在井下,如何能够安全高效地实现压煤的回收,成为压煤所占比例较大的矿区当务之急,条带开采结合充填被普遍用于回收压煤的有效方法。文章以某矿条采煤柱工作面为背景,运用UDEC软件进行模拟研究,验证条采煤柱的稳定性,为解放"三下"压煤起到理论补充。＂ Coal resources under three＂ strip mining is widely used, but the strip mining ended, there are nearly 60% of the coal in the coal pillar is a permanent legacy in the underground, how can safely and efficiently realize the recovery of coal, a coal accounts for a lar- ger proportion of the mining area, a pressing matter of the moment, strip mining with filling is commonly used for effective recovery method of coal. Based on the background of a mine strip coal pillar mining face, simulated by using UDEC software, verify the stability of strip coal column ,for the liberation of ＂coal resources under three＂ pressure coal play a theoretical supplement.
