千米深井巷道间岩柱荷载分析及其合理间距确定

Load Analysis and Reasonable Interval Determination of Rock Pillars of Roadway of 1,000 m Deep Mine

根据压力拱理论,结合极限平衡区应力分布规律,研究了非均匀应力场和均匀应力场下的巷道周围应力分布规律,确定了相邻巷道间的合理间距,为深部相邻巷道间的煤岩柱留设距离提供了参考。

In this paper, according to the pressure arch theory, combined with stress distribution law of limit equilibrium region, the author studied stress distribution around the roadway under the non-uniform stress field and the uniform stress field,and determined reasonable interval between adjacent roadways, which provide references for designing interval between coalrock pillars of adjacent roadways in deep parts of mine.
