| 摘 要： | 通过对某煤矿高冲击危险工作面开采过程的三维数值模拟,揭示了近距离煤层下部煤层在煤柱的影响下,在有冲击危险的区域,变形局部化剪切带与高压应力共同作用于煤岩体上,在变化的剪应力作用下,脆性岩体容易发生剪切破坏,并在瞬间释放弹性能,形成冲击矿压。

| Abstract: | 3D numerical simulation of mining coal with high bursting danger in a colliery reveals follow results: local shearing zone of lower coal seam within closed coal seams and high compression stress both act on coal and rock body in areas with bursting danger under the influence of coal pillar.Under the influence of varied shear stress,brittle rock body is liable to be sheared and discharge so much elastic energy in short time that rock bursting comes into being. |

| Keywords: | mining engineering distortion localization shearing zone 3D numerical simulation rock bursting |
