摘要
通过对综放工作面顶煤破碎特点和过程的分析 ,初步揭示了综放工作面端面冒顶机理 ,指出顶煤破碎区提前至煤壁前方和某些诱发因素的影响是导致端面冒顶的主要原因 .由此提出了控制端面冒顶的主要技术途径和措施 ,在现场应用后取得了满意的效果 ,有效地控制了综放工作面的端面冒顶 ,实现了稳产高产 ,从而形成了综放工作面端面冒顶治理的系统关键技术 .图 6 ,参 10 .
After analyzing breaking characteristic and process of roof coal in fully mechanized sub level caving mining face, roof falling mechanism of face area is revealed tentatively. It is put forward that the combination of advancing broken zone of roof coal to ahead of the faceline and influence of some inducing factor is direct cause. So main technology approach and measures of controlling roof falling of face area are advanced. With these measures, a satisfied effect of controlling roof falling has been procured in practice, consequently, a systemic key technology of controlling roof falling in sub level caving face is formed in the paper.6figs.,10refs.
