摘要
通过进行综放工作面仰斜开采顶板初跨规律及围巷稳定性研究,可合理指导回采工作面在初采老顶跨落期间的顶板管理以及合理确定风运两巷超前支护参数、排水巷与切眼间煤柱,为首采工作面围岩结构分析提供了新的思路和方法。
Study by the fact that mining stride over for the first time rule in fully-mechanized coal winning caving roof face and surrounding rock stabilization,we can direct coal winning mangangment and support parameter, this afford new thinking way for analysis surrounding rock structural.
