摘要
针对铜川下石节煤矿软岩巷道底臌问题,通过对巷道工程地质条件进行分析,总结了底臌发生的原因,设计了有效的控制软岩巷道底臌的支护方案,并利用数值模拟软件对支护方案进行了数值模拟分析,最后,通过工程实践证明,此支护方案是有效并且可行的。
According to the floor heave of the soft roadway in Xiashijie Coal Mine,analyse the geological conditions,generalize the cause induce the floor heave,and an effective support technique was designed to control the floor heave.At last,engineering application of the support technique in Xiashijie Coal Mine show that it is effective and practical.
