摘要
该文以成庄煤矿为背景,采用有限元法对成庄煤矿某工作面进行了数值模拟。着重讨论了开挖宽度对于采场周围应力场的影响。计算结果显示随着开挖宽度的增大,顶板、底板最大应力以及采场边角剪应力水平都有所增大。最后对计算结果进行了总结,进而对传统的采场应力场作了改进。
Based on Chengzhuang mine stope, one of its working faces is numerically simulated with finite element method. The impact of evacuation width on stress field around the stope is particularly discussed. The results show that both the maximum stress of top plate and baseplate and the stress of the stope edge shear increase along w/th excavation width expanding. The calculation results are summarized and thus traditional stope stress field of is improved.
