摘要
随着矿井同一盘区、不同层次的逐步开采,由于特殊的水文、地质条件,会出现下层盘区部分地段巷道与上层盘区对应巷道的不重叠布置,因而出现了对应上层盘区采空区煤柱下的特殊应力区,对此在应力分布及支护方式上进行了研究。
With different gradations of the same panel in the mine mining, there is no overlapping arrangement between section roadways of the lower panel and corresponding roadways of the upper panel because of the special hydrogeology condition, special stress area under the goaf pillar of the corresponding upper panel is appearred, and the paper studys the stress distribution and the support mode.
