大采高单体液压支柱工作面过断层方法

Method of Passing Through Faults at Face with Large Mining Height and Single Hydraulic Props

为了解决大采高工作面过断层难题,采用单体液压支柱控制顶板的方法,采取一系列安全技术措施,有效地控制了工作面的顶板,保证了该工作面顺利过完所有断层,取得了较好的经济效益。

In order to solve the problem of passing through faults at the face with large mining height,the methods of controlling roof with single hydraulic props were proposed.The technical measures for safety were adopted,the face roof was effectively controlled.The face smoothly passed through all the faults encountered.The better economic effect was obtained.
