Analysis on the Control of Wall Caving at the Island Working Face with Large Mining Height

就大采高孤岛作业面片帮控制开展探究,结合具体工程实际,在分析大采高孤岛作业面煤壁片帮原因的基础上,对实现煤壁片帮防有效防治的措施作出针对性总结,并对措施的实际应用效果进行模拟分析,其结果表明防治措施效果良好,能够实现对煤壁片帮的有效防治。

This paper studied the control of wall caving at the island working face with large mining height. Combined with specific engineering practice, this paper analyzed the reasons of the wall caving at the island working face with large mining height, made a targeted summary of the measures to effectively prevent and control wall caving and carried out simulation analysis of the practical application effect of the measures. The results showed that the measures were effective and could effectively prevent and control the wall caving.
