巷道垮塌堆积体的数值模拟研究

摘要

运用 CDEM 模拟软件，对回采巷道上覆岩层进行数值模拟，探讨了巷道垮塌堆积体内部块体之间的力学关系，得出的结论对巷道的设计施工有一定的参考价值。%Using the CDEM simulation software,this paper made numerical simulation on mining roadway overlying strata,discussed the mechan-ical relationship of tunnel collapse deposit and internal block,the gained conclusion had certain reference value to the tunnel design construction.
