大采高作业面顺槽支护设计分析

Analysis on Design of Crossheading Support for Working Face with Large Mining Height

以大采高作业面顺槽支护设计为对象开展探究。结合具体工程实际,在开展作业面矿压显现观测及分析的基础上,对顺槽围岩支护方案做出具体探究,提出"锚网索+二次注浆"的联合支护工艺,并对相关方案的应用效果做出监测,希望能够为其他矿井相似工程的开展提供借鉴和参考。

The design of the crossheading support for working face with large mining height was designed.Combined with the actual project,on the basis of the observation and analysis of the underground pressure of the working face,this paper made concrete study on the surrounding rock support scheme of the crossheading,proposed the combined support technology of"anchornetcable+secondary grouting".The application effects of related schemes were monitored.It is hoped to provide reference for the development of similar projects in other mines.
