Abstract
In this paper, taking the Sima mine 1215 working face as the actual engineering background, analyzed the stability of fully mechanized top coal caving face end zone from the surrounding rock structure of the end zone, coal pillar structure and coal pillar reinforcement way . The arc triangle formed after roof collapsed was as large structure in the end zone, the end support was as a small structure. According to the method ensuring the stability of the large and small structures, the end bracket which is suitable for the characteristics of Sima mine is preliminarily selected.关键词
