连续跨采底板巷道围岩移动变形规律研究

Study on Surrounding Rock Deformation of Floor Roadway Affect by Continuous Overhead Mining

为了研究连续跨采采动对底板巷道围岩移动变形的影响,拟借助FLAC3D计算工具,以上社矿区为研究对象,对其盘区石门巷道跨巷开采进行模拟计算。通过对围岩移动变形数据进行实时监测,结合压力拱假说相关观点,对巷道围岩变化以及煤层底板应力变化数据进行分析。

In order to research the influence of mining move to surrounding rock deformation of floor roadway,to use the FLAC3D calculation tool to analog computation for panel cross-hole basic on the rock origin data of shangshe diggings. At the moment through the data monitoring of sun＇ounding rock moving and deformation, and combined with the pressure arch hypothesis relevant opinions to analyze for displacement of roadway roof and roadway＇s sides and stress data of the floor of coal seam.
