Design and Numerical Simulation Study on the Support Parameters of Working Face Level Alley
In order to further improve the boring efficiency and safety of soft rock roadway,it is especially important to realise the efficient support of soft rock roadway.Taking 1121 comprehensive mining face as an example,based on the comprehensive analysis of its geological conditions and its support status quo,the support parameters of anchor rods,anchor cables and top mesh were optimised by using the dynamic information method of anchor rods and site conditions;the support effects before and after optimisation were compared based on FLAC3D software,and the expected results were achieved.
