掘进工作面围岩应力分布特征及其与支护的关系

Stress Distribution of Heading Face Rock and its Relationship with Support

以具体工程为实例,利用软件分析掘进工作面的围岩应力状态,并采用实际监测的方式获得真实的应力状态分布,分析工作面的薄弱区域,给巷道支护提供依据。支护方案能够改善围岩应力状态,限制岩体间的相对变形,起到有效的加固支撑作用。

Takes particular project as an example, employs software to analyze heading face rock stress state, and uses actual monitoring way to get the real state of stress distribution, to analyze weak areas and provide a basis to roadway support. The supporting scheme can improve the state of rock stress,limit relative deformation between the rocks, and play an effective role in strengthening support.
