UDEC 在沙曲矿煤层单巷掘进防突中的应用

摘要

By means of UDEC5.0, the paper simulates and calculates the stress in the surrounding rock of a single roadway head in high gas-outburst coal seam of Shaqu Mine, obtaining the stress distribution condition in the coal on the both sides of roadway, thus optimizating the the prevention technique of excavating a single roadway, which is significant to prevent coal and gas outburst effectively and excavat a sin-gle roadway in coal seam rapidly.%　　本文应用 UDEC5.0数值模拟及解算了沙曲矿高瓦斯突出煤层单巷掘进工作面围岩的应力，得出了巷道两帮的应力分布状况，在此基础上优化了沙曲矿高瓦斯煤层单巷掘进防突方案，对于有效防治煤层单巷掘进工作面煤与瓦斯突出，实现煤层单巷快速掘进具有重要的意义.
