垂直重叠巷道安全距离分析研究

Study on Safety Distance of Vertical Overlap Roadway

针对某矿在巷道掘进过程中需要解决两条垂直重叠巷道的安全距离及巷道支护问题,文章采用理论分析、FLAC3D数值模拟、理论计算和现场实测的方法,确定了两垂直重叠巷道的最小安全错距和支护方案,并通过现场矿压观测验证了支护方案的可行性。研究成果不仅可以为本矿井提供借鉴而且可以为其他类似情况的巷道支护提供参考依据。

Accordance with these problems of safe distance between vertical overlap roadway and the support when roadway excavation, the safe distance between vertical overlap roadway and the support were identified through the methods of theoretical analysis, FLAC3D numerical simulation, theoretical calculation and field measurement in this paper, and the practicality of support were validated by min- eral pressure observation. Resuhs of this study can provide a reference not only in this mine but also for another similar situtions roadway support.
