软岩底鼓巷道围岩控制技术研究

Study on Surrounding Rock Control Technology of Floor Rock in Soft Rock Floor

底鼓是煤矿巷道中经常发生的动力现象.本文本文以某煤业公司戊8半煤岩软岩巷道为基础, 对巷道底鼓产生的因素进行分析, 并利用FLAC3D提出合理的底鼓控制方案, 在现场应用中取得了良好的技术经济效果, 为类似巷道底鼓治理提供了参考依据.

The kick drum is a dynamic phenomenon that often occurs in coal mine roadway. This paper analyzed the factors of the floor kick drum based on the soft rock roadway of the E85 coal rock of a certain coal company, and used FLAC3D to propose a reasonable bottom drum. The control scheme had achieved good technical and economic results in field applications, providing a reference basis for the treatment of similar roadways.
