本文采用有限元法对不同型式掩护式支架性能进行评估,模拟十种不同形式的掩护支架,对这些支架在控制工作面下沉、防止沿长壁工作面早期顶板垮落以及避免围绕底板端部过多应力集中方面的性能进行了分析。对于不同的顶板条件推荐出与之相适应的掩护支架。
This article uses finite element method to evaluate the performance of different types of shield support to simulate ten different forms of shield support, sinking of these supports on the control surface, preventing the roof collapse along the longwall face and avoiding the end The performance of excessive stress concentration was analyzed. For different roof conditions recommend the appropriate shield bracket.
