摘要:在调研现有淮南矿区煤巷围岩稳定性相关资料、实测部分深部矿井地应力、回采巷道
围岩力学参数的基础上进行数据整理、分析,得到淮南矿区深部回采巷道属于高应力软岩巷
道,赋存于典型构造应力场下。调研发现淮南矿区深部煤巷变形表现为:底鼓严重、顶板开
裂呈现“W 型”垮冒、帮部出现网兜现象;采用 UDEC 数值模拟计算分析了巷道变形破坏部
位及其原因;针对破坏特征提出了淮南矿区深部回采巷道支护思路并进行了工程实践,结果
表明:巷道围岩变形得到有效控制,满足了工作面安全高效生产需求,取得了较好效果。

Abstract: Based on relevant literatures of surrounding rock on tunnel, in-situ rock stress measure
and mechanical parameters testing, it shows that which is in deep roadway of huainan area
belongs to high stressed soft rocks under typical tectonic stress. The deformation of tunnel
manifest to be serious floor heave, “W” type cracked on the roof and department
phenomena appear on sides of tunnel. UDEC numerical simulation was adopted to analysis the
failure section and reason. Support ideas were proposed according to the failure characteristics and
were put into engineering Practice, the result shows that: deformations of surrounding rock were
effective controlled and meet security and high efficient production need, and good results have
been acguired.
