房山矿区四槽煤冲击地压模型试验及数值模拟研究

Study on rockburst of No.4 seam in Fangshan Mine by simulating experiment and FEM

文章针对北京大安山矿房采区－１００水平四槽煤发生的严重冲击地压，在实验室进行了模型试验研究，完整地模拟了开采过程和冲击发生的情况，从顶板的下沉量分析了冲击地压发生的必然性，同时采用有限元数值计算对此进行了验证，并提出相应的防治措施。

Abstract Based on the serious rockburst of No.4 seam,-100 M level,Fangshan Mine Zone,the model tests are done in lab for simulating the whole process of mining and rockburst.According to amounts of roof convergence,this paper considers the rockburst is inevitable,in the meantime,verifies it with FEM Method.In the end,some control ways are presented.
