【摘要】 软岩巷道底臌是煤矿井下巷道经常出现的矿压显现之一,也是引起整个巷道支护系统破坏失稳的起点。通过对不同支护方式和不同底板加固方式所引起的巷道周围应力场和位移矢量等的计算分析,全面论述了底板加固对软岩巷道的作用与影响。更多还原

【Abstract】 Soft rock roadway floor heave is one of the ground behaviour often taking place in underground coal mines,and it is the damage initiation of the whole support system.Through the calculation analysis of stress distribution field and displacement vector caused by different support method and floor reinforcement,the effect of floor reinforcement on soft rock roadway is discussed.更多还原
