对于各种不同的地质条件,分析不同类型支架的性能,可以选出合理的掩护式支架架型。本文采用了有限元分析方法评价各种不同类型的掩护式支架,并模拟了10种不同类型的掩护式支架架型。通过对控制工作面顶底板移近量、防止顶板沿长壁工作面早期冒落及避免在支架底座前端部产生较大的应力集中的分析,推荐适应不同顶板条件下合理的掩护式支架架型。 For a variety of different geological conditions, analyze the performance of different types of brackets, you can choose a reasonable shelving bracket type. In this paper, the finite element analysis method is used to evaluate various types of shelves, and 10 different types of shelving models are simulated. Through the control of the work of the roof near the amount of floor to prevent the roof along the longwall work face early to take off and avoid the front end of the bracket base to produce a greater stress concentration analysis recommended to adapt to different roof conditions reasonable shelving bracket type .
