大采高孤岛作业面回采工程控制

Control of Mining Engineering at Island Working Face with Large Mining Height

大采高孤岛作业面回采过程中极易出现煤壁片帮、两巷顺槽变形等现象,这对井下的生产作业持续开展和井下人员安全有严重威胁。针对这一点,就大采高孤岛作业面回采工程控制开展探究,结合具体工程实际,在分析大采高孤岛作业面煤壁片帮、顺槽变形等原因的基础上提出针对性的控制技术,并对其应用效果进行分析,希望能够为其他矿井相关工程的开展提供借鉴与参考。

Rib spalling of coal walls and deformation of roadway crossheading are easily appeared in the process of island mining with large mining height, which posed a threat to sustained underground production and safety of underground workers. For this,this paper studied mining engineering control at island working face with large mining height. Combined with specific engineering practice, this paper proposed corresponding control technology based on the analysis of rib spalling of coal walls and deformation of roadway crossheading at island working face with large mining height and analyzed its application effect, which hoped to offer reference for related project of other mines.
